Do you apply RTV to the diff itself or the diff cover?
What is the torque specs on the diff cover bolts?

I always RTV the cover, but that's up to you. 80 ft/lbs sounds like a lot for diff cover bolts, I was thinking it was somewhere around 30. You need 3 qts 75w140 and 1 4oz bottle of friction modifier if it's a limited slip.

Make darn sure there is no oil draining out on the sealing surface. If there is any oil there you will have a leak afterwards. Someone posted that Autozone sells a gasket. If so, I recommend using a gasket.
