I like it. Those look like 69 camaro RS reverse lights. 67s would be a little smaller and flush mount. I am really not a fan of the round mustang style. I get confused and see too many exhaust pipes. Here is the 67 rs vs 69 rs
Fish; you are correct, they are the '69 RS backup lights...good call! The '67 lights being flush would be on an angle that I didn't like. The '69 lights come out flat, even though the valence is at an angle.
