I`m working on a chevy monza and I`m replacing the stock gears of 2.56 with a posi 3.42 out of a S-10. I found out the pinion has a larger bearing and the yoke spline is a different size.I`m assuming I have to replace the race to match the bearing size but I have no idea what to do about the yoke size. Any and all help will be great. Thanks
