im buyin 42 TSLs this month but as of now my truck sits with a 14bff in the rear and a d44 upfront .my 60 is in my garage awaiting new hubs and some other little things before i put her back under.so i was wondering if the 44 would hold up to 42s just for riding around on street?? . one other ? im having a hard time finding the rear u-joint for the 14bolt. Is it a 1410 or a 1350 i keep tellin the guys at the auto store its a 1410 and they dont believe me.
