This was from my father in laws' 1977 GMC High Sierra truck-I believe it's either the original or at least a correct era one. The truck had a dealer installed CB too which has an adapter behind the station select knob and the 3 wires are still there. CB wasn't in the truck when he got it but the stereo works fine! Clean, hard to find factory stereo. Asking $100 shipped. I'll also add your desired length of new wiring using the OEM stereo plugs too!
