3rd Gen 8.5 10 Bolt Rear

[Maxmilion]

I have an 83 Caprice and would like to upgrade the rear end to an 8.5 or 8.6 10 Bolt. I think any 3rd generation B-Body rear (77-90) would be a direct fit... First, is my research correct and second, how would you go about obtaining one.... Thanks a million... Max

About the only way is to run across a 9C1 that is being parted out, the wagon rears have slightly wider mounts. I have heard of people using them but the bushings are in a bind. 4th gen 91-96 8.5s will bolt in fine. But will have the 5x5 bolt pattern so you need the front stuff too.
