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

Wow guys, I have had quite a few more people asking for an early A adapter.
OK to help me out here how "Early" are we talking here?
What is it, 64-66 Barracuda are similar, I think the Darts are similar from 64-66 as well?
So are what all are you hoping for?
By the way!!!
There may be a perk in it for a few select people here, since I dont have all these cars at my disposal. I may need a few owners to get me some incredibly good measurements, and in return I will give an adapter to them.
We will see what I can come up with on my own, if anything then Ill be sure to ask for some help where needed.
Help me solve which cars and what years we are talking about here first.
Also, its possible that it may not be worth the cost if there arent enough people interested in the particular model for a specific adapter. So I also need to know how many people want them and for what car specifically.
Let me know guys. I am on vacation right now and may be able to jump on the design next week sometime.
Lata'!!!!!!

'63-'66 Valiant/Barracuda will be the same and honestly from looking at the two, I don't think there will be any difference between them and what you would need for a '63-'66 Dart.

Truth be told, I don't see why this won't work on an early-a as is. It's been a few years since I've had anything post '66, but I don't notice any difference, or at least not one I can remember.

Let one of us early-a'ers try one out, quickest way to sort it out. You should be able to find someone in the TMC willing to help out, if you don't let me know and I'll see about making a trip down.

BTW, how much were these beasts going for again? I was thinking it wasn't too awful much. I might would be willing to just bite the bullet and get one, the gas cap I currently run already leaks and doesn't look anywhere as cool as a flip top.
