Gas Cap for 1965 Barracuda

Now that's some beautiful work. I am very impressed with your skill! Have you tried taking any hard RH turns with a full tank of gas yet, to see how your seal ring does at keeping the gas in the tank? I'm guessing it works quite well in that regard, but that's just a guess.

Interesting technique, making the cap tamperproof by requiring a special tool to remove/install it. Some questions occur to me:

• Is there some kind of a protective bumper on the underside of the tool so the cap's surface doesn't get marred?

• Would it be possible/easy/feasible to make a version of this cap that has a handle built in/built on like the original?

I will very likely buy at least one of these caps for my '62 Lancer. Would probably want to buy two tools, though, so I could put one in the glovebox and one somewhere else in case the first one gets lost!
