For Sale Gas cap for early 57 to early 60s wagons

[Big Bad Dad]

This is an aftermarket gas cap that I have had for many years. Part# G-26. The old package is in rough shape. The cap is still sealed inside the dirty plastic, so I can only assume the chrome is still OK. The applications printed on package include Dodge and Plymouth "full size" station wagons 1957 to 61. It lists Chrysler wagons 1957 to 65 "except C body" (I am a bit confused by that, but I am thinking the cap would probably only fit up to 1964?)
Asking $25 plus shipping from Fincastle, Va. 24090. (Probably USPS priority mail box)
