I have one in OK shape, it's not perfect just a bit faded, it's just the board w/screened artwork and the wiring though, not populated. I can get you a pic if interested. It is original and dedicated, not an overlay.
Would love to see pics. Are the metal pieces that are used to clamp it into the cab there? I have controls I can put in it. The wiring, board, and holddown clamp pieces are the critical pieces. Thanks!
