Unique GMC Hood Ornaments

Thursday, February 11th, 2010

The big news for GMC in 1936 was the introduction of their first 1/2 ton pickup. Though GMC now shared cabs with Chevrolet trucks, the visual exterior differences were mostly noticeable in front of the hood.

The GMC grill was totally redesigned and did not resemble the Chevrolet truck. This unique grill was modified little between 1936 through 1938 but the top grill ornament was changed with each of these years.

Watch for these ornaments at swap meets, antique shops, and older vehicle trade shows. They are extremely rare! Even locating the real thing for the following photos was very difficult.

The first year for the newly designed GMC 1/2 ton (cab shared with Chevrolet trucks) and the last year for the exterior radiator cap. This example of flowing artwork rivals even nicer automobiles of that year.

The hood must be raised to reach the hidden radiator cap but a fixed die cast logo (similar to 1936) remains the focal point at the top of the grill.

1938-1946

GMC extends the smooth front hood hold down upward several inches and eliminates the die cast letters. This chrome extension (not like Chevrolet) can be just as rare as the early style. Once off the truck at a salvage yard, it soon becomes mixed with scrap iron because of no identifying GMC letters.

Hub Caps-Used 15 Years

Thursday, February 11th, 2010

Many of the tech articles on this web site emphasis’s the subtle ways that truck parts were made economically by GM. Truck often received Chevrolet car items that were used the year before. Sometimes even other GM brands sent their older items to be placed on assembly line trucks.

Of all the ways GM saved money on truck parts, none is more unique than the savings on 1/2 ton hub caps. Chevrolet pickups used the same baby moon style hub cap from 1940 through 1955. The skins and basis are the same. A relative inexpensive addition was simply changing the lettering or emblems on the outer brass skin. They required a change in tooling, not expensive for a company the size of the Chevrolet Motor Division. The stamping department just kept making the same base and skins. The skin surface stamping changed as was required by the design department each year.

Check the following pictures. The base hub caps are all the same. Some of the car hub caps are the same as the trucks. Even GMC trucks decided to use these caps between 1947-55. After all, just placing the three GMC letters on the skin added much savings to the company’s bottom line.

Early GMC Hood Side Trim

Thursday, February 11th, 2010

GMC entered the light truck market in 1936. They shared some sheet metal with Chevrolet including the two tops of the four piece butterfly hood. However, the hood sides were not the same and certainly their trim was totally different.

Two designs of the General Motors Truck logos were used during the years of the side opening hoods. The 1936-37 hood sides held a narrow horizontal logo plate above the air vent openings as in attached photo. The right and left were the same. A more streamline design began in 1938 and was carried through 1946. Its rounded point on only the front creates a different part on the right or left.

Counterfeit Hub Caps

Thursday, February 11th, 2010

Companies outside the Chevrolet Motor Division have always produced replacement parts for the aftermarket industry. Manufacturers begin reproducing non-original parts very soon after a new vehicle is introduced.

A problem occurs on decorative trim such as hub caps. Here, Chevrolet (and other manufacturers), display their logo to attract positive attention. To reproduce a Chevrolet hub cap, non-GM companies have at times altered the bow tie logo. In this way, they have avoided legal action by GM and market a hub cap that was close to the original. Their hope is that most people would not notice the small changes. These caps were usually produced in the 1930′s ‘ 40′s and marketed through auto parts stores or by mail order.

In today’s world, these caps have become very rare as few collectors use them on their vehicles. GM has now given approval for reproducing these obsolete correct logo caps and most collectors want the real thing. The few remaining ‘counterfeit’ caps have a place on your garage wall with their unique history.
