I use lube lockers for the 72 front and rear without an issue - no leaks, easy to remove and clean up and you usually can get 2-3 uses out of them if your careful.

I use the black oil resistant RTV on the 69 front and rear without any leaks or issues but takes a little time to clean and prep when you pull the 3rd member out or front diff cover. You don't need a ton of RTV, just 3/4 bead, make sure you go around the outside of the bolt holes and studs.

I coated the paper gasket with Indian Head Gasket Shellac, and assembled. Seems to work fine last couple of years.

Ymmv of course, any of the above solutions would work. :)

Andy I use anaerobic gasket maker. As long as both surfaces are clean and flat that stuff will seal and will not leak. Works incredibly well on machines surfaces.
