This pic was with caption of 'looking for rear grill for 63 Corvair' Almost same, but doesn't come up in pics of 63 Corvair? 1968s slotted car grill - Bing

Ding ding!! I think we have a winner!!
Similar but not exact......................however searching Corvair rear grill found this. Looks to be an exact match :thumbsup:
