For those not requiring the original seat cushions on their 1955-59 Task Force truck, a roomy comfortable substitute is available. This unit is from a 1988 and newer Chevrolet or GMC truck and is almost a bolt-in.
The legs or side brackets on this newer seat comes attached to the cushions from a used truck and sets nicely by the floor edge of the 1955-1959 cab. It almost looks factory installed! Yes, the cushion edge will slightly touch the doors but cause no closing problems.
The result is a much softer seat and a definite increase in distance between your “middle” and the stock steering wheel. No interference with the in cab fuel tank.
