RARE A body Radio and Cassette Recorder

I have two one in my Duster. I installed a CD player in mine. Mounted right in no mods. Looks like it came there. I found one in a 71 Monaco and one in a 4spd. Demon. Seen many over the years. Casset will not work without the radio it came with. plugs into the back and is used for volume control. You can record or talk through your speakers. Monaco had a speaker mounted in the grille. I only ever saw them in 71's
