Ok all - I got a good education on what to use to seal 'er up for every scenario....Now she's sealed and will NOT leak (I hope)
What is the best gear lube to run in the pumpkin?
It's a standard width A-body 8 3/4 with a 4:30 - 1 Richmond gear and Richmond Spool turning Dutchman Axles.
It will see track/street time maybe 70/30?
Again, it's been almost 30 years since I've put one back together, and my Dad used to use regular rear end lube, and would always bring me the magic bottle of Direct Connection "Whale Oil" additive that smelled horrible!!!
I'm sure technology has advanced since then!
Thank you again in advance,

Wally.
