[QUOTE=Ed Snyder;69856]Back in the 1970s, I myself was guilty of defacing GMC doors by cutting holes for stereo speakers. Since car stereos weren't available until 1969 according to
https://www.caranddriver.com/feature...-of-car-radios, it's highly unlikely a dealer would have installed your door speakers. Today I wouldn't dream of cutting a hole in a door like that.
Interesting point Ed; the existing wires are connected to to the remains of the speakers, but not to the original AM radio. it hadn't occurred to me that a separate stereo would have been installed but that certainly makes sense.
