The 4spd should work nice with a tall gear, the granny low could compensate for the higher ratio. It would be like having an overdrive. I think the GMC's all had rear leaf springs(unlike most of the Chevys which had the coil spring rear suspension)so that should make it a little easier to find a rear end to fit. I have a 66 GMC parts truck, the rear end under it is supposed to be out of a 79' Chevy four wheel drive, and other than being wider from wheel to wheel it seems to fit perfect. And being from a four wheel drive it still has the 6 lug hubs. The hard part would be finding a four by four with the tall gears. My brother had a 78' Chevy 4 by 4 with 3.08 gears, but I don't know how common they were.
