I have a 1970 12 bolt rear from an impala casting number on housing is 3894860NF . Axle code is GM 0304B . I am trying to identify this rear and it 's ratios . Can anyone help me by answering if this is a standard casting number on 12 bolt posi's rears? I was told this uses camaro gears and to do more research.
