i did a super quick look, and the only valve i came up with, was some kind of universal type [i think] with button head allen screws holding the end caps on where the valve is put together.
i did, however, find an unused cigarette lighter from a mid 70's newyorker !
i may have a couple other places to look, and if i find anything, i'll let you know.
six or seven years ago, i gave a plastic valve to my buddy for use on his 55 chevy. i know it was a mopar valve, but i don't remember what it was. he sold the car last year.
