I have the same numbers matching 69 in very good condition with the am radio. I put in a rediRad unit, it goes inline of the coax wire for the ant. It has a 1/4 in. connector the can plug in a ipod or mp3 player. Tune the radio to certain freq. to play your music. I have 12 gig. of music on my phone so lots of tunes. I didn't cut anything up or have wires running front to back, just a + and - for power. Sound old school with the one speaker which is good for me. But others have the hidden radio units with the cd changer or something along those line. Just depends what u want to spend and what kind of sound you're looking for.
