Thinking about rebuilding my 9bolt
So i wanna get the rear rebuilt in my car it has a BW 9 bolt with 3.27 gears currently. I want to go to 3.70s or 4.11s so might as well get the whole thing rebuilt. Was just curious where the best place for parts is and what I could expect to spend if I have a shop rebuild it? I know every shop is going to be different but just a ball park estimate would be nice

Re: Thinking about rebuilding my 9bolt
I just pulled a BW 9 bolt with 3.70 Motive gears and a low mileage stock posi that holds >65lbs breakaway torque. It was rebuilt a few years ago with all new bearings/seals and has a TA rear cover and LCRB. PBR brake brackets but no calipers or rotors. PM me if you are interested. I'm in Alabama so freight shouldn't be too bad.
