hey there maybe yall might be able to help me. I've got a '90 3/4 ton dodge single wheel base and I lost the rear end out of it. well I found a '89 1 ton dually rear end and thought that would work and it some what works cause it sits just fine on the springs but the inner portion of the fender well on the bed sits in the middle of the inside duals and the leaf spring is about .5" away from the duals. the frame on both trucks are the exact same, as well as the length from spring to spring and the rear ends are wider like expected so what do I need to do to fix my problem. I really don't want to put spacers on it because I don't want to put extra strain on the bearings.
