Thanks a lot for your help. You are right that they are hub piloted wheels but if you go into a parts house looking for those type of lug nuts they look at you like you have two heads with horns:) I want 16 inch wheels. I would like to run tubeless wheels. I actually bought some new production 7.50x16 thinking I would use the old wheels but they are very rusted. Come to find out the new tires are tubeless, Made in Thailand. I was using a slag hammer to remove chunks of rust and went through the wheel. The used wheels I have looked at have much larger lug bolt holes. Not sure what size they are but the old ones are 1/2 inch. for the half inch stud.. I would run the tube type wheels if i have to but aren't they the split or two piece wheel. Thanks for the help. BTW FYI I own a 61 k-10 Step side. This 62 c-30 a 65 c-20 mostly for parts and a K-20. A 52 GMC I think it is a 100. And a 57 GMC that has 350 in the grille with a 270 CID I think. So I might be on here a lot. smile
