thank you for your replies, I have these chrome 8 spoke wheels but I can't find a stamp anywhere on them and just wanted to know what they were, not sure if I should hang on to them or not. I ended up going back with the original wheels I had found and powder coated them to match the top and put the hub caps on.Correct. Nothing but plain old white or gray/silver/“argent” steel wheels on early Broncos. The color depending on the year.
Anything spoked, or anything chromed was either added at the dealer or by a previous owner.
There were probably some similar options on later full-size bronco‘s and F150s that might be similar, but they would still be an add-on for an early bronco. And if they are truly spoke type, like we used to call “wagon wheels”, then they probably were not original to any year.
