Checked out the search engine and couldn't find anything relating to this problem.

I have a '68 Chevy C20 swb dually. The wheels are 16"x6" 8 lug 6 1/2" bolt pattern and are hub piloted on a 4 5/8" center. The main problem is, these are two-piece wheels with an eccentric ring that holds the tire in place and requires a tube-type tire.

I want to change these to a later model wheel that will accept a radial tire. From all the info I've gathered so far, I'm resigned to the fact that I'll have to change the studs from 1/2" to 9/16" which is no big deal, but I have yet to find a wheel(s) that will fit. I'm not a purist, this doesn't have to be a GM wheel. My goal is a safer ride with a one piece wheel and the radials.

Any idea's???
