I still ask, are you sure it's an 8.5" 10-bolt? They only came in '84-'87 Turbo Regals and '84 Hurst Olds, and '85-'87 442s. If it's the original rear from your Regal, at best it would be a 7.5" rear with 3.08 gears; most likely it's got 2.41s or 2.56s though. If it's not original, then you gotta do some research; find out what it was from, or pull the cover and start counting teeth.
