wheel stud problem...

sorry. i researched and my actual knurl size is .570 at least thats what stock size is supposed to be i like the gm .580 but i still don't know how id get em in there?

If you don't own a press, there should be a machine shop or weld shop in your area that would do it. - Should cost next to nothing. The last time I tried to research stud knurl sizes, the general consensus I found was to have a hole that is about .003 undersized to get a good press fit. I helped a friend press in some studs in an 8&3/4" that he put Yukon axles in. We couldn't find the proper knurl size so we had to drill his holes out bigger before pressing in the studs.
