Thanks Edman and Krue for your replies,

I stopped at the local parts store and rummaged through their bins of wheel studs. I was able to find ones for the front since the knurled part of the stud on the the truck are the same as the modern 14mm studs,19/32". I think they are listed as ones that would fit a 2001 Tahoe.

Looks like I may be stuck with the rears though, they appear to be only about1/2", according to their computer. I thought about drilling out the axel and drum large enough to fit the new studs but I am concerned about getting them perfectly centered. I'm going to have to think about this some more.

I will pull off the rear wheels tonight and maybe knock out one of the studs and have a look.
