I have a 57 stepside body on a 74 1/2 ton frame. The rearend that is on it now is a few inches too wide. I have to raise the bed off the frame so the outside of the tires won't rub on the outside of the fender wells. I have the factory GMC wheels for a 74. I'm 58" from inside to inside on the drum housing. I have a 4" gap from the back of the drum housing to the leafspring. I'm looking for a compatible rearend that is approx. 54" wide and has a gear ratio in the lower 3's for freeway driving. My 454 and turbo 400 have to work too hard to get my truck up to 60mph. I was hoping to find something close so I can use the same driveline. Any help would be appreciated.
