What's your pinion angle? Did you have a drive shaft made up for this? Are you still using the ball and trunnion joint out of the transmission? Are the u-joints "phased" correctly? Lot's of stuff to check. Let us know.
Everything is stock except the 8 3/4. I bought new u bolts for it also. I am going to have a drive shaft made later on. I was just hoping the one in it would work to test the rearend.
