I found a ebay auction for the 1973 center caps for the slot wheel. Advertised as mustang caps. http://cgi.ebay.com/ebaymotors/ws/e...578921242&viewitem=&sspagename=STRK:MEBIDX:IT Kind of cool to know there out there. All someone would need is some screws and some maverick inserts and there good to go.
