The Stovebolt Site Forums The Shop Area Engine Shop Understanding rear ends

Those Caprice Classics were often used as cop cars and then turned into taxi cabs. Both Police and Taxi companies do a good job servicing their vehicles. The Police versions of the caprice came with beefed up brakes and suspensions which included posi/limited-slip rear differentials. After scouting several in the junk yards I found most of the 10-bolt posis under those caprices were 62" from mounting surface to mounting surface, had 5 on 5" bolt pattern, 12 drum brakes, 3.42 gears and an oversized rear swaybar that would be perfect under these trucks. I was going with a slightly larger rim so needed a 64" wide differential with a 5 on 4 3/4" bolt pattern to match my front disc brake conversion.
