Hola
The first FM's for the Imperial line showed up in 1964. And yes the radio is
built by Delco. Even tho it looks as the Caddy/Buick built unit from Delco
the face plate has differant sizing. If your '64 to '66 AM/FM has a
operating problem you can use the GM model as a spare parts supply. I did
this so that I could get my '66 radio in proper operating manner. The the
other differance is the GM version does not use 8 ohms as the MoPar family of
audio speakers and the antenna up/down switching is built into the radio.
