I have a Posi rear end removed from a 1963 Buick Wildcat. Not sure of the gear exactly but looks to be around a 3.42??? This is a complete rear end, was supposedly rebuilt. The rest of the chassis was all rebuilt, front end etc, so would believe this was also. Comes with new brake parts installed, drums, control arms, springs and the panhard bar and most of the original brackets. If it unbolted, it is here! ASKING 675.00. These needs a good home! PICKUP ONLY IN CHICAGO HEIGHTS, IL 60411 PM For my contact info
