I sent to a message to ebay seller because of incorrect description and also to remind those here searching what to look for (if you haven't seen http://www.thecoralsnake.com/ ). The ebay auction- https://www.ebay.com/itm/1960-1970-Center-Hubcap-552030-1968-Shelby-Ford-Truck-Mag-Chevy-GTO/153060850836 - I thought you should know that the 68 Shelby hubcap uses the part marked 552562 . The one you show in auction will not work because the Shelby concave emblem will not conform to the indented surface of the 552030 part. Just thought the info might save a Shelby buyer from returning a item and shipping involved because of a incorrect description. Best of luck with your auction. Bob Gaines Shelby concours judge.
Thanks Bob!
Now I need to worry about catching HUB CAP ANXIETY! Great. Just great! ::)
