I ended up ordering some custom wheels from Stockton Wheel in Stockton, California for my 1948 two ton. They realized there is a need for these wheels and seem to be quite knowledgeable on what will work with the clearances. I am getting 22.5 one piece wheels to replace my original 20 X 6 3 piece wheels. Just couldn't find a reliable place to get some used ones. In the long run, I think it is the better idea, just going to cost more. If you are interested in some wheels for old Chevy's you might give them a call. 1-800-395-9433. I talked to Frank.
