DANA 35 differential question
I have a 4 cylinder 5 speed 1995 YJ and I was working on the rear DANA 35 differential and I broke the pinion shaft lock bolt in the differential case. I tried drilling out the bolt but I may have toasted the threads which would hold the bolt in the case. The pinion and ratio ring are okay, but I think I'll need to replace the case. This may be a stupid question but, I was wondering if I were to buy a used (DANA 35) rear differential case that was on a 1991 6 cylinder, 5 speed YJ (with 3.07 gear ratio) would I be able to change out the gears in the case back to 4.11? I greatly appreciate any advice at this moment.
