Were they standard installed on 95 Z28's? My rear end blew out and when they oulled the cover there was an auburn posi unit inside.. Im replacing it with a eaton heavy duty now.

 

hey i was wondering if you sent the cme valence out yet??i havent herd from you since i sent you the money...can i get a tracking number please....o yea your pm box is full

 

There are three version of Auburn posi's, the base posi, the pro center, and the full race... Some FBodies came stock with the clutch based Auburn base model posi, while others came with a gear based Torsen posi I believe. Not sure which one was the option.
