Thanks for the info. I have a 95 Impala with that rear. There is however a difference in the width on a Caprice, Impala and 9C1 police car. Also, the bolt pattern is a 5 on 5 compared to 5 on 4.75. Do the original axles fit in the caprice rear end? A better choice would be a buick road master rear end with the trailer package. It should come with 3.42 gears instead of the 2.93 or 3.08 gears. I think that package also was avaialble in the fleetwood, but not 100% certain...
I believe my car has a built one already, so I will have to see. As for the Imp rears, you can't rebuild the posi, so we generally go with the Eaton posi as a replacement. The stock one didn't last long in my Imp before I was getting the one tire fire. The Eaton is whats in my Imp now with 3.73 gears.
