Picked up these Wildcat letters years ago. Not sure what years or where they fit on the car but they are in great shape and all pins are good. $50 shipped.
There are two sets of the 1968-only italics letters for sale in one listing on eBay right now....... https://www.ebay.com/itm/255459858863?hash=item3b7a9819af:g:dMsAAOSwm3tiQgQa
