The elusive early-A AM/FM & other stuff

Wasn't the AM/FM radio a dealer installed option?

Believe it could be ordered new, it was shown in the standard radio section of the 65 parts book. It did not show in the sales brochure but those are in general semi-accurate. At any rate they seem to be quite rare. I know other AM-FM radios will fit but I just think the factory 65 is more cool!
