Mike, not sure what wheels you are using, but on my Fairmont, I have been using the 5/8" Strange wheel studs since I switched to the Jerico 4 speed, 17 years ago. I have Centerline Autodrags, and the bigger studs fit my Centerlines with no modification required to the wheels. The studs have a thin sleeve that threads onto the stud, that fills up the space in the lug holes of the wheels, and the lug nuts are flat, flanged units, with flat aluminum spacers that go between the face of the wheel and the lug nut flange. No more of that hassle with shank style lug nuts galling up inside the holes of the wheel.
