8-3/4 with no gear oil :(

Just for future reference........

Anytime I assemble a differential the lube goes into the assembly.

If it will not be used for weeks / months etc., I store it on jack stands so the axles can be turned once in a while to make sure the internals stay covered in a protective film of oil.

Case in point. This photo is from an original Dana 60 assembled in 1969. It was stored inside for decades without spinning the axles.

You can see how over time, the moisture that entered via condensation caused rust to the point of pitting on the ring gear that was exposed above the level of the lube.
