i have a 66 that I’m putting back together, and I’m trying to go back to original...it was pretty stock when I got it. Anyway, it had an after market radio mounted above the windshield when I got it and of course an antenna. The antenna was mounted on the passenger side, in front of the door . So here is my question. Would a 1966 40 even have a radio, and if so where was it mounted? Thanks for any insight!
