4.11's would make more sense to me. The calculator I was using could be off some i suppose. Ill try jacking up the rear end tonight to see if it matches what workinlonghorn said. I'd do it this morning but I'm going to Oreilly's Autofest with a couple of friends. Either way I'm going to want to try to find a 3.73 differential to drop in this thing.
