Lugnut King may have what you are looking for, but they won't have the manufacturers center emblem. You can find these on their site on Ebay, but I'd contact them with your measurements to make sure they will fit. Good luck with your search.
eBay is what we've been talking about. I've been able to find a blank center cap (which I'm fine with), but the center to center was incorrect. I need a ctc on the bolts to be 2-1/8". All I've found that are unbranded have been 2-1/4". There was an American Racing cap that was said to be 2-1/8", but I don't want to give American racing credit for a wheel they never made.
