I've got a spare set of wheels like that available, Vectors from American Racing. They were available on 70's Vettes, and were seen on the Dukes of Hazard Dodge. I have a pair of 7x15's and a pair 8.5x15's. Standard Chevy bolt pattern.
I also have a set of 10x15 on a 5x5 bolt pattern.
They are are used and show some nicks, but overall in good condition. I also have 4 matching center caps.
Send me a PM if you have interest.
Dave
