Don, this is in the FWIW category, as my BJ8 is a late March 67 build, but I do have the original keys. The keys have the markings as yours as yours with a FS series hex key for the ignition/door ; but the glove box trunk/key is not round. It is also a FS series, but is shaped like a rectangle with rounded corners- dimensions 1/2 x 1 inch. Dallas
