Hey, so recently I got a new ring and pinion gear setup for a 1997 F250 HD 7.3l, front and rear, with a ratio of 3.55 in the rear, and 3.54 in the front, instead of the original 4.10 and 4.09 setup. The front is a dana 50 ifs, while the rear is a sterling 10.25. I then bought some bearings for the pinion gears. Neither bearing fits either pinion gear. Now obviously, it would be tight, but they are actually a bit far away from working. So that brings up the question. What is the bore diameter for the front and rear pinion bearings? Or, if not that... What is the pinion shaft diameter, either at the splines, or the closest part to the pinion head? Thanks!
