I know where I can find a lot of g body bodies. I was wondering if there was something in vin or on car that will tell me what rear end it has. Most of these cars are sitting low cause no wheels can't really see what is what. Most are regals and four door cars, some elkys and few montes. Nothing that sticks out. Looking for a 8.5 to rebuild. I know finding a good 12 bolt would be even harder. I have a 9 in housing got from a friend all brackets are on it, but wanting all chevy.
