OK, Heres my dilema I have a HP D44 out a a 3/4 pick-up, the one w/ the bigger tubes and hubs from another project. Its already setup with a detroit and 5:38s. The brakes, seals etc. are all new it was in a show truck. I also have a D60 but its stock no locker, gears etc.would need all new hardware etc. I dont plan on running anything bigger than 38s. I'm still running a 4.0 so I dont think there is enough power to really break parts. Thoughts, comments appreciated. Thanks Jason
