[RCP57]

I drilled in from each side toward the center so luckily I only had the issue with the one axle tube. I installed bushings that are 3/8 OD so by drilling in very slowly with a 9.5mm bit I was able to get the larger bit to cut straight(almost) and in the end be able to press fit the bushings. Its a few thou out but you can shove a single axle all the way through both sides. It just doesn't turn as nicely as the other axle but I think it will be fine. When you put an axle into the diff gears from each side it spins freely. It definately made me sweat for a while though. I have way too many hours into these housings to wreck one now.
