Most of it covered . Add that drivetrains are very different . GMC used their own 6 Cylinder engines and V-8 engines that were borrowed from Pontiac . GMC trucks also used Dana rear ends on the 1/2 ton trucks. For some reason GMC used a lot of phillips screws where Chevy would use a clutch head . Different deluxe heater box to compensate for the differences in the dash . Some of the GMC trucks would have a large pipe brace from the upper cowl to the frame . I have seen them mostly on the Napco trucks but also ran across one on a 3/4 ton two wheel drive .
