After letting the Ultra Black setup I added some Penn Grade 1 80w-90 (formerly Brad Penn oil) along with GM additive. Let it sit for about 30 minutes with the carrier facing upward and no leaks. Next was throwing the axles in with the c-clips and installing the carrier pin and finally buttoning up the diff cover. Also dug out one of my NOS diff gaskets.

EDIT

One thing I forgot to mention. I also took a file to the mating surfaces on the cover and housing. Applied a thin coat of Ultra Black on the housing, placed the gasket and then applied a coat on the cover. Cross-pattern on the bolts and good to go.
