Yes Like BGH said could be RS emblem. I was just thinking possible Z/28 emblem? 1968? But it does look like round 67 side mirror in pic. Too bad you don't have more Pics. I would still post it on "Lost Muscle Cars" Good luck, you never know

I see nothing in the current '67 Z Registry (240+ cars) that is a match for that car. Best of luck with the search.

My old car is similar. 67 Z Nantucket Blue, RS Black Vinyl but it had white stripes, Blue Interior with headrest seats and it was an original 4.88 rear end car. But it was from California originally.
