1955 Second Series-66 Chevy Truck Model I.D.

1955 1966 Truck

We hope the following information on Axle, Transmission and Model identification will help many of you with your questions. Accuracy was a concern as we compiled this information. Because GM made so many scheduled as well as unscheduled changes, there is much discussion about these changes.

1963-1966 Power Steering

Thursday, February 11th, 2010

1963-1966 Chevrolet Power Steering

Chevrolet linkage-type power steering is now available optionally on Series C10, 20, 30 models. This was formerly a dealer installed item. The equipment consists of a hydraulic pump, power cylinder, control valve, relay rod and hoses.

The power cylinder is mounted to the frame and is connected to the control valve through the hoses. The control valve is mounted on the steering drag link between the knuckle arm and the steering arm and it serves to control the flow of pressurized power steering fluid to either side of the power cylinder piston. This in turn pushes or pulls the tie rod as required for easier steering.

Power steering helps to combat driver fatigue and aids maneuverability. It also dampens road shocks and vibrations at the steering wheel and provides extra comfort and ease of handling.

1966 Stepside Back Up Lights

Thursday, February 11th, 2010

The rear stepside fenders on the 1955 through 1966 are usually considered the same. The reproductions on both metal and fiberglass are listed in catalogs and related advertisements as being identical on the right and identical on the left.

Not true if you are a perfectionist! In 1966 Federal automotive regulation required all cars and light trucks to have back-up lights. Thus, GM modified this fender with a stamped indention to better fit the required back-up light assembly.

1960-1966 Back Up Lights

Thursday, February 11th, 2010

To keep vehicles base price low, GM made many items dealer accessories. If the buyer required extras, the dealer was the installer. This created less complications on the assembly line and added more income for dealerships.

One of these extras was back-up lights on the 1960-1966 Fleetside pickup. After 35 years they have become very rare due to their location below the taillight assembly. They were always subjected to water and salt. Corrosion of the chrome outer die cast bezel is a normal result of trucks used regularly.

The adjacent photos show the light assembly before installation plus their correct location on the pickup box.

1964-1966 GMC Custom

Thursday, February 11th, 2010

With increased prosperity in the USA during the 1960′s the demand for more extras on cars and trucks was high. Manufacturers followed this trend with additional features, at least on their top of the line models.

GMC followed this movement even though their product was mostly for work related duties. While sharing much sheet metal with Chevrolet, they certainly did not want to look like their competitor so GMC designers made a point of adding no deluxe features to the new ‘Custom’ truck that would relate to Chevrolet.

What must have been a limited budget is reflected by the inexpensive trim on their new custom cab. The post behind the doors uses three pieces of straight anodized aluminum butted together to fill the space.

What looks like an amateur creation was truly a factory design. It almost appears they needed paint divided strips for their two-tone paint option! A more expensive piece is the curved side window trim with the unusual groove to fit into the door lines.

For their custom cab GMC chromed their pre existing white grill, V-6 hood side emblems, bumpers, and hub caps. Thus, their design and manufacturing costs were lessened. Even the stainless windshield trim was already available from the Chevrolet division. A new small chrome Custom emblem on the door post is an exclusive GMC only part. (This die cast emblem was also used on the rare deluxe model GMC Suburban.)

The remaining GMC ‘Custom’ feature appears to be the paint scheme when two-tone colors were ordered. Here designers seemed to have gone to excess. No copying Chevrolet here! There must have been a 20 minute meeting on the telephone in 1964 to decide which color went on which metal body panel.

The accompanying photos are from a 1964-66 GMC Custom ½ ton pickup that was seen parked along the street. The owner was not available for comment.

The wear on the original paint and trim give no doubt that it was an untouched factory GMC. Its pure condition deserved ‘a second take’ and the following pictures were a result.

Note: Even on the Custom GMC pickup, the large back cab window was optional. Many did not want the extra sun on their neck or in the cab during hot summer days. Therefore, this deluxe cab was ordered with the small rear glass.

1960-1966 Chevrolet Differences

Thursday, February 11th, 2010

To keep production costs down during the 1960-66 Chevrolet truck series, GM made very few changes on their ½, ¾, and 1 ton. Only the more skilled truck enthusiast can correctly identify each year in this series. Keep this following data close at hand when you evaluate these years.

1960

1960 1966 chevrolet differences 1

1960 1966 chevrolet differences 2

Dual headlights. The sheet metal part of this hood will be used only two years. The Apache name on the side plate carried from the earlier series. The Chevrolet letters are stamped in the bottom of the grill housing.


1961

1960 1966 chevrolet differences 3

1960 1966 chevrolet differences 4

A grill modification places the Chevrolet letters in the center of an insert. Half ton wheels change from having three clips to three nubs in their center to secure a different design hub cap.


1962

1960 1966 chevrolet differences 5

1960 1966 chevrolet differences 6


1963

1960 1966 chevrolet differences 7

1960 1966 chevrolet differences 8

Only year in the series with round headlight rings. The side fender emblem is more vertical in shape. The final year in the series for the classic wraparound windshield. This also will change shape of the doors and result in a completely redesigned dash. This is the big year for major mechanical changes. A new design short stroke 230 six cylinder is standard. The famous 235 six (1954-1962) is history. Torsion bar front suspension (1960-1962) is replaced with the more conventional coil spring front end.


1964

1960 1066 chevrolet differences common 9

1960 1966 chevrolet differences 10

Basically the same truck mechanically and body. GM has a good thing going! The noticeable exterior differences are the chrome side emblems. The flatter windshield is a trade mark of these four years.

1960-1966 Chevrolet Cab Trim

Thursday, February 11th, 2010

Though at first, a new person in the GM truck hobby might think all 1960-66 Chevrolet cab trim (only on the deluxe models) is the same. In reality no less than three changes occurred during this seven year body style.

During 1960 (maybe into early 1961) the optional stainless cab side trim on the Chevrolet truck was designed to attach to a long connecting horizontal trim strip. After production began, GM discovered that new owners could easily dent this more delicate trim. When carelessly throwing items in the bed or during fast stops, cargo could hit the stainless. This problem was solved by discontinuing this horizontal strip. The connecting ends of the side trim were then modified to show no evidence of a past attachment (see photo)

Therefore, side trim part# 8768843 and 8768844 as well as the horizontal strip #8768842 are very difficult to locate 45 years later. Most 1960 truck restorers must compromise and use the more readily available 1961-63 side trim.

In 1964, a major change occurred in the construction of this cab trim. Chevrolet followed the trend of other new vehicles and also began using aluminum trim. It was anodized to keep its shine and the production cost was less. It required lower pressure to be stamped as compared to the previous stainless steel. Thus, the tooling lasted much longer.

1966 Cab Data

Thursday, February 11th, 2010

With the introduction of the new Cameo in 1955, GM added their most deluxe features as standard equipment. This “Boulevard Pickup” was to stand out above all others.

For the person wanting his 1966 Chevrolet pickup restored to exact originality, authentic data is difficult to find. Most General Motors books from that year have been discarded and aftermarket books are usually far from being complete or accurate.

Therefore, the following data will be of great value to the perfectionist who is restoring a 1966 Chevrolet pickup to exact factory appearance. The pages are direct copies from a rare 1966 Chevrolet truck salesman’s data book. This is the final authority on how your truck originally came from the factory. It should settle any arguments on your restored 1966 Chevrolet.

1960-1966 GMC Deluxe Suburban Seats

Thursday, February 11th, 2010

The seats on this 1962 GMC Suburban are pure factory original. Their shape is designed for only the Suburban body. They allow for access to the rear seat.

Horizontal white vinyl in the back rest is characteristic of many GM vehicles during this era. It was an extra touch that added a little extra flair to the deluxe models.

1966 Cab Features

Thursday, February 11th, 2010

1966 cab features

Curved Windshield

The large one-piece laminated safety plate glass windshield has an area of approximately 1116 square inches.

Electric Windshield Wipers

Provide constant wiping action regardless of engine load or accelerator position. Wipers have 13-inch blades and a wiping speed of 110 strokes per minute. Two-speed wipers, including a push-button-operated windshield washer, are standard. Wiper arms and the metal portions of the blades have a matte finish.

High-Level Ventilation

Outside air enters through louvers at the top of the cowl – away from road dust, heat and fumes. The air passes into a plenum built into the the cowl, where water is separated from the air and drained out. Air enters the driver compartment through two inlets-one on the right side and one on the left.

Ventipanes

Partial opening of ventipanes permits stale air to be drawn out of driver compartment. Ventipanes can also be swung wide open to force outside air into the compartment. Made of solid safety-sheet glass.

Rearview Mirrors

Standard mirrors on Pickup models are a left-side fixed arm and an inside shatterproof. Series 10-30 Chassis Cabs utilize left- and right-hand 6-1/4 inches fixed arm standard mirrors. Series 50-80 models have a left-side 17-1/4 inches swing arm mirror as standard. A wide assortment of optional mirrors is available on most seines. See the Optional Equipment listing in the Model Specifications sections for exact availability.

Full-View Rear Window

Available as an option at extra cost. Large solid safety-sheet glass area of 762 square inches (331 square inches for standard solid safety-sheet rear window) improves rearward visibility to make driving easier and safer.

Safety Glass

Series 10-50 models have door windows of solid safety-sheet glass. Laminated safety sheet glass with metal window frames is optionally available. Series 60-80 models have laminated safety sheet glass with metal window frames as standard equipment.

Soft Ray Glass

Tinted glass is available as an option at extra cost. It may be ordered for the windshield only or for all windows. Consult the model specifications pages for availability as it varies with the series. The light and heat absorption of this glass reduces eye-strain and helps keep cab temperature more comfortable.

Window Frames

Painted metal frames on series 60-80 give extra rigidity to windows and reduce likelihood of broken or cracked glass. Metal frames are also included with the laminated glass option on Series 10-50.

Door Locks

All cab models include a key-operated left door lock as standard equipment. A right door lock is available as an option at extra cost.

Running Boards

Cabs in Series 50 through 80 are fitted with a running board on each side for ease in entering and leaving the cab. LCF cabs also have two convenient steps on each fender.

1960-1966 Chevrolet Hood Changes

Thursday, February 11th, 2010

1960 1966 hood changes 1

The two distinct styles of hoods during this seven year series (1960-1961 and 1962-1966) were each the same for Chevrolet and GMC except for one slight difference. The spot welded insert across the front (5″ x 82″) is a different stamping for Chevrolet than for GMC. This created a changed appearance with less expense!

Because of this different insert the two trucks have park light lenses that will not interchange. For economic reasons the 1960-1961 style hood was soon discontinued by GM. After the mid 1970′s, if the dealer ordered a 1960-1961 hood, he was sent the 1962-1966 style. It fit the older design truck perfectly.

For the non-perfectionist, all 1960-1966 GMC and Chevrolet hoods will interchange.

1966 GMC

Saturday, July 1st, 2000

Owner: Ed Snyder

1966 gmc pick up truck

My truck is a 1966 GMC three quarter ton pickup with a short Fleetside bed. This truck came to me with the original factory build sheet showing a build date of 6-6-66, and factory equipped with the optional 351 cubic inch V-6, turbo 400 transmission, power steering, power brakes, 4.10 locking rear end, heavy duty springs, and custom cab. It was originally a two-tone truck, green and white, but I had it repainted a 1973 Cadillac color, Sage Metallic. It has just over 50,000 actual miles on it. I’ve owned it for about 5 years. I bought it from a neighbor who had bought it at the estate sale of the original owners about a year before. It was in great shape – no rust and no dents.

About a year ago, I finished a complete restoration of this truck which took me about 18 months. The running gear (engine, transmission, rear end) was in excellent condition, due to the low mileage. The paint, however, was badly oxidized. It now has far more paint, and far better quality paint (Sikkens) than it left the factory with. Although the truck is stock mechanically, I took the opportunity during the restoration to perform some comfort and cosmetic upgrades, such as: carpet with heat-resistant sound-deadening mat underneath it, carpeted door bottoms and kick panels, new seat padding and upholstery with inflatable lumbar supports, tachometer and clock, electric fuel pump, chrome plated valve covers, Thermo-dyne coated exhaust manifolds, dual exhaust, interior tailgate latches with cables to replace the original chains, spray-on Armacoat bedliner, and hitch receiver built into the original step bumper.

I’ve taken it to many car and truck shows since the restoration was completed. It’s won trophies or plaques at nearly every show, including second in class at the West Coast Truckin’ Nationals in Paso Robles, California in March, 2000.

During the restoration process, I acquired catalogs from about a dozen of the largest Chevy/GMC restoration parts suppliers across the country. I tried ordering parts from most of them, just to see how they compared in price, service, and parts availability. Although I had a couple of bad experiences, such as my credit card being charged right away, but waiting several months for the part after being told it was in stock, most of my experiences were good. I must say, though, that my experience with ordering from Jim Carter was unsurpassed – great customer service, quick shipment, and quality parts!

Ed Snyder

Editors note:

I learned that GM didn’t build any short bed 3/4 ton pickups. When I asked Ed about his truck being a short wheel base 3/4 ton, he sent me the following e-mail. Nice truck Ed.

Steve

…. This truck is definitely a three quarter ton short bed. It came from the factory as a long bed (127″ wheelbase). I shortened the frame 12″ behind the cab and cut another 8″ off the tail end. The wheelbase is now 115″, and a short bed bolted on perfectly when I was done. I don’t know if anyone else has ever done this, but it draws a lot of attention at the car and truck shows it’s been in.

Let me know if you have any other questions.

Ed Snyder

NEWS FLASH!
