I have a rear axle off of a 1 load 1972 or 73 GMC (cant remember wich yr it was 2 wheel drive truck.) had a G,2,3,4, and reverse manual transmission in the truck so its geared low. wheel seels do have to be changed and fliud changed eh the ubolts are brand-new and 9 leaf springs to the stack eh.
I also have one sturdy lift gate that came off of my gmc 3500 dually 8 ft by 12 ft flatbed. When I took it off 4 years ago do not see why it wont now when hooked back up appropriately eh, it worked fine. 1200 or best offer. some trade negotiable. this is a heavy beast
