Rear main seal install?
Hehe.. I think you guys are talking about 2 completely different things 
For the Rear Main Seal.
GM has a tool for doing it.. but I used the shadetree way:
You need to loosen all the bolts on the cover to allow the seal to position itself correctly. I used a piece of 2x4 and lightly taped it in with a hammer. Once the seal is home, re-tighten all the cover bolts.
For the Moser rearend seal, you need to post in the Drivetrain section
