Gas cap orientation

I looked back at the pics of the car before I disassembled it 3 years ago and it was clocked correctly. Every job putting this car back together has a glitch.
My 70 Swinger gas cap looks like Dana67Dart s. It clocks correctly, but it sits maybe 1/8" below the quarter. Maybe add a thicker gasket to raise it?
