My '30 Ford Rat Rod is leaking rearend fluid out of the main seal. After I change the main seal, what kind of gear oil should I use?

It is a 9" ford rearend with an unknown gear ratio.

Please help!

Rearend Gasket?

ok, cool.

Do you know how to determine what type of 9" Ford rearend I have in order to figure out the exact gasket I need for the Rearend axle housing?


Thanks

That's what I thought, but when I look it up there seems to be quite a few different versions of that gasket. How do I figure out which one is correct?
