Those are Harley center covers......I just ordered a pair off of EBay for 40 bucks. Part number 83841-09
Are those the same as the ones that come on the F150 Harley truck? Those are the center covers I'm getting for my wheels as soon as Willy Shinny sends my new chromed wheels. They have some more on ebay, but say they are the F150 HD center wheel cover. They don't give a part number. I think I'll send them a question. Sure save a lot of money.
