Will a short box fit if I took off my long box from a 1990 GMC Sierra 1500?
No, what will you do with the extra 2' of frame sticking out? Cut it off?
you would have to cut the frame, shorten the driveshaft, adjust the wiring, modify the exhaust, modify the fuel lines, and probably a few other things that I am missing.
Wont fit. Trade it in and get the truck you want!
