When I bought my car, it had the following gas door on it:



It has the indentation at the bottom of it. I really like the look but am not sure if it is correct. I have seen different gas doors and actually have one that is completely flat.

Which is correct?

FWIW, the front grills on my '68 appear to also be for a 1967. And my car came with a round mirror(March '68 build date). After I bought it, there were some signs that I missed during the purchase process that would indicate the car was in a wreck at some point.
