1967 GTX, 1968-69 Cuda/Barracuda flip door. Gas cap

Jaws, when I googled some info for research. I inserted the Mopar part number and not only did it tell me that this one was for the A-body 68-69 Barracuda and might be installed on early 70’s A-bodies as well. But the 67 GTX was also mentioned so I threw that into the mix. If I’m wrong by giving out wrong information I didn’t mean that. It’s just what I read. Thanks, Al
