I have an OLD OTC one I got from a dealership auction back in the 80s. I just went on Ebay and found this.
DELUXE+PLUS DANA 30-80, 8.8 FORD, G.M. 10-12 bolt DIFFERENTIAL HOUSING SPREADER | eBay
Heck, I might get that, too, because it pretty much does them all. If it'll do the Ford and GM, I just BET it'll fit the Chrysler 8 1/4.
