Check ebay. I check regularly and bought a set for $50 each in good condition with the centercaps. It took me months to find them at that price but if you are persistent and check every week you'll find them. Don't buy into the notion that you have to pay $500 a set like some guys charge on here.
I got a set of 5 with no rock rash or scratches. I'm sell'n for one of the other techs here at the shop. He's gonna get me some pics so I can post 'em. Call the shop if interested. 904-998-9625 ask for Tom.
