put in 8 3/4, now have vibration
That U joint looks like a conversion 7260/7290
and the shaft is sadly too short now. There should be about 3/4-1" of shaft showing at normal ride height. You got 3 options: new longer shaft, SS springs that move the axle forward a few inches or a DANA 60 rear that is longer in the snout - $$$.
The U joint are both internal circlip and should self center with no play. Tap in cap and put Circlip on, tap on the other and itll seat the opposite one with just enough to get the 2nd circlip on. The Diff side is easier, the clipped caps just seat in the yoke and the straps bolt on.
