Is there any reason you need to keep the 7 1/4? There are other options, for rears, that are easier to get parts for. Also as stated, the rear might or might not be the problem. Find out for sure, first.
Nope no reason except maybe cost of finding the right one. Would be stronger. I guess I better learn how to make sure its the rear end. To this point it has burned up all the oil twice and last time into the shop it was very hot to the touch. Those are other reasons I suspect the rear. If I could teach myself how to figure out a bolt on 8 I would make the move.
