I used a "lubelocker" gasket.
A bit costly, but reusable and no goopy rtv to scrape off.

I ran 70-90 RoyalPurple in front.
75-140 in the back.
Recomended if you tow a trailer..........and id use it just in case anyways.

Don't take my word for it, look here:

use "The Right Stuff" its more like the factory sealant and sets in 3 minutes. ive never had a leak when i use it. also i use lucas gear oil or 80-90 and a tube of friction modifier in all my lsds and lockers. makes it run smoother and work wayyy better
