1967 Newport Custom. I want to change my gears from the 2.76 to 3.23 and swap springs, but I also have a hard time putting anything dirty back into the car when I take it out. I think if I'm going to go to the trouble of pulling the rear end to swap the springs and gears then I should also consider rebuilding it all.... I have new green bearings installed already (prev-owner), but have never taken it apart. Is there anything I should look for or replace while I'm tearing this apart to clean and paint? Anything I should be aware of with these bearings so i don't damage something? I'm thinking center gasket, inner axle seals, outer brake plate gaskets and front spring bushings. Already have the rear bushing and shackles. I'm assuming the outer seals were replaced with the bearings.
