Early A Flip Top Gas Cap ADAPTER

wow 62' Hmmmm, Im trying to get a local guy here to let me come over and measure a few things on his 64' Barracuda, but I'm not sure I know of anyone that has a 62 Lancer. I guess I better clarify. I'm thinking 64,65,66 Valiant Barracuda, and Possibly Dart. I have to get together with a few members from the local club to take a few measurements if I am going to get too many versions made. "TMC" I have had some members here wanting to help by giving measurements but since I am selling them and people obviously expect them to fit correctly. Id like to make sure of the measurements I have.
Hell that's why I have a job, people misunderstand others explanations all the time!
Ill say this for you REALLY early A guys. Let me get the 64-66 done and Ill see if I can round up a 62 or so to check out as well.
Thx guys!
