Ask and you shall recieve! (Flip Top Gas cap Adapter)
Update................................
I finally had a chance to measure a 65 A body. I will be making the new design and having some produced hopefully by the end of the month.
I found that while the other on will work it could stand to be a bit thicker on the early 64-66 models. However I was able to check this on both a Valiant and a Barracuda. Both are the same.
On another note, the current one I have will also fit the typical d-150 type trucks. I havent looked into it a whole lot, but we placed it on the truck and it would def. work.
Ill keep you all posted. Chances are Ill post a new thread about the new version of adapter.
Later guys!
