Ask and you shall recieve! (Flip Top Gas cap Adapter)

So I am 1 of three cars that is a '74/75 ?

Here is a pic of filler neck...there is a thin cork washer between the car and the filler neck..

Hope you can help us ?







Installed..


This pic caught my attention.. I need a little clarification, as my adapter fit perfect.. What I noticed is your filler neck appears to mount on the outside of the quarter.. (like the slid it in from the outside and bolted it down... On my 69 Dart it was exactly the opposite.. the filler neck was mounted to the inside of the quarter. only the heads of the screws were on the outside of the quarter... did Ma Mopar do it 2 different ways?? Or was mine a fluke? Anyone else have any insight on this?
