Consider going to 3:42 or 3:73 if you are going to pull the diff out. Not much more money to find new/slighty used 3:42 and sell off your unit! Just my .02 :D

Birch.

When you go to get the seals and o-rings, make sure they are the latest. What I found was that the dealer sold old style stock and not the latest part.
I had to have him order the latest part number because I know the seals were updated.
