I have a set of 4 16x10 steel welded wheels with 3.5" backspacing built buy Stockton wheel with factory center caps. $600 plus actual shipping. These will work on 40s, 55s, 60s, and 80s. I bought them for a project using 80 axles but I'm unable to complete the project at this time. So I'm selling off some of parts I gathered for that project.
