    Need help identifying rear I have. Right side of axle tube stamped letters are OK. N. 166(see attached) Pass side#1385724 F. I know it's a 8.2, it has bop cover, non c clip axles, I believe rear is out of A body but not the year and OEM car. If anyone can identify it I sure would appreciate the info. Thank you

    I can't find OK in the axle charts. Maybe it's an ON, and the K was a mistake. That would be a 3.64. Take the cover off and look at the ring gear markings.

    So it's a 2.93. 41/14 = 2.93.
