I made the mistake of not providing my shop with the gaskets and seals requred for the rear differential. They're tearing it apart in order to put in a 3.90 ring and pinion. Kerven Subaru can't have the parts to me by Monday, and that would greatly delay the project. No local parts houses have anything aftermarket.

My questions:

Could I use a form-a-gasket product to seal the rear differential plate?

Could I re-use the wheel gaskets and o-rings?

What do you guys think?
