There are video`s on YouTube showing the rebuild of differentials....The one that I just recently watched was from " ERIC THE CAR GUY" Very informative.
He explained the pinion shimming and showed it being installed.
I highly recommend seeing it. I believe he was working on some 80`s Ford...
but the process is the same...
