8-3/4 REAR AXLE SEAL INSTALL ??

I guess I should have mentioned there are aftermarket axles of some kind with the "green bearings" and no adjusters on the passenger side axle. I bought the car "as is" and there's a lot of really nice parts on the car I'm just trying to fix all the little "bugs" while sitting idle waiting on this corona b.s. to be over. You guys STAY HEALTHY AND STAY SAFE!!!
