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

I would like one. I have a 76 Duster. Also, do you know which flip cap is best/preferable or which one I should use, and where I can get one easiest? Sorry to hit you with all the questions at once, but I have been thinking of doing this for a long time and found this thread through dumb luck. Read through all 48 pages...LOL! Thanks for your time.
