Chris,
The diff is from a 510. I have removed the cover and inspected and all looked good. I don't know how to tell the difference between the two ring gears, however, I will check it if you tell me how to tell the difference. I may also have a spare 391 limited slip, I would have theck. I am in the Jacksonville are and run Robeling, Sebring. If you want to discuss it my cell is 904-583-8649
