I have an 8.25 1973 Dart rear that has been compleatly gone through. All new bearings, seals etc. New clutch type limited slip ( detroit I think need to look ). Gears are stock. Spring purches have been moved in about .8 per side to allow for tire clearance. It is in my stock 1968 plymouth Barracuda. I didn't want to tub it so I move the springs in board as much as possible without cutting anything. Move your front spring perches and buy offset shackles and you are home. The housing has been sandblasted and black powdercoated, looks like new. I only have about 50 miles on the rear as my motor is out for replacement. I have about $ 1450.00 in the work ( done at a good local shop) would sell for $ 1200.00 or make me an offer. My car will not be needing it any time soon.
