    I want to either upgrade or replace the rear in my 1973 Buick Regal. I believe it has the 8.5 10 bolt with the bolt-in axles (granny gears and an open diff). I have added gears and a posi into a chevy 8.5 I am not against doing this myself. Anyone have a link to the correct bearing kit? Also, any preference on gear manufacturer and posi? I am thinking 3.42 gears (or possibly 3.23's).

    The alternative is to find someone that sells a drop in replacement that is set up the way I want it. I kind of doubt there is anyone out there...but I figured I would ask!

    There are some bolt in axle 8.5's (71-72 Buick and Olds). Others are C clip like the 80's GN's. I'm not sure about the 73 Century/Regal.
