Ask and you shall recieve! (Flip Top Gas cap Adapter)
Have you developed an adapter for the early A bodies? I know you mentioned you would be working on one. I read the whole thread and this is a great product.
There was an article in a Mopar magazine a few years ago where they recessed into the panel of a 68 or 69 Dart the flip cap from a Barracuda. Much body work and refitting the filler tube. Doable, but this is a eaiser way and can be undone.
Put me on the list if it fits a 66 Barracuda!
