Here are a few pics of there rear end rebuild that took place some time ago when I still lived in Colorado.

The original rear end had 3.07 gears and a factory Posi.

Since I've been planning an overdrive transmission from the beginning, I settled oil 3.73s. Because of the ratio split on the case, I had to go to a 4-series carrier which was just as well because the factory Posi had spun a bearing on the carrier.

The replacement Posi is just a Eaton with the carbon fiber clutches. I like the drivability of these and they have plenty of grip for my purposes.
