I believe that those wheels are OEM. Most likely off of a later model Ford of the early to mid 90’s vintage rather than the 1982 wheels that came on the truck.
Poor communication on my part. Though I did use the word “updated”, the “not at all stock” referred to the production of the truck itself, but I now see that those words could easily be construed to indicated that they are not Ford production wheels, which they indeed are.
