I retro fitted a factory AM/FM, cassette, CB from a late 70`s Cadillac to my 78 with no mods if I remember right. I have been told that these where available as a dealer add on to the trucks but was very expensive. They are set up for 4 speakers and are digital. The best part about them was the built in CB. You could listen to the radio and if a CB signal came in above where you had your squelch it would cut out the radio and you could hear the transmission and then automatically go back to the radio. Perfect for off-roading or road trips. It didn`t have a high powered CB but it wasn`t bad. Its rare to find a working set though. Make sure you get the mike, head unit, and second box.
