gas cap alignment on 65 barracuda

Hi all
I am getting my 65 ready for paint and wanted to do a body color gas cap.
Mine bar isn't parallel to the ground when tightened.
I think that is the look they were meant to have.
Anyone know of a fix? I searched but found a lot of other leaking issues not handle fixes.

I saw the sweet billet ones for sale by a member, but would hate to paint that.

Thank you for the help!
