Hey Dan,
The wheels I have are Cragar SS cast aluminum wheels. They were made a couple of years ago and have been discontinued by Cragar at this time. I did notice another company selling a very similar, if not the same wheel-http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=330349226893&viewitem=&sspagename=STRK%3AMEWAX%3AIT
The wheels I have are 9" with 5.5 backspacing on all four corners, with 275/40/17 Firestones on all four. I have a little rub on the front when I make extreme turns in a parking lot. Hope this helps.
Jamie
