Dana 30 rebuild

[Warthog]

Ok so I’m rebuilding my Dana 30 on an 87 Cherokee and a comanche. Bought a race install tool. The one that’s aluminum with all the changeable discs. Which one fits the races? Yes this does sound like a dumbass  question but I have two that may or may not fit as I have no clue how these should fit the race!….first axle build ever so please forgive my ignorance. I’d assume it’s supposed to fit flush and snug but one doesn’t flush and the other slips just inside the edge. I don’t wanna groove my races which I know are harder than Lithuanian math equations….trying to keep my terminology clean, I think one is 73mm and the other is 68? Something along those lines anyway. Anyone know what size I need? Do I have the wrong tool kit? Help anyone pleas

I had the same issue with my race installer from Amazon. I have previously installed races with a drift and hammer.  Precision fit between the race and driver are not necessary. The important part is not damaging the bearing contact surface and be sure it's seated. Try flipping the cup piece on the driver and see if the back side is a closer match the the race size.
