Finally got around to filling the radio hole in the dash. In the blue truck we put a RetroSound unit which does look nice, but 99% of the time I'm listening to satellite radio or something from my phone so a full head unit isn't required. Since I'm running an amplifier for the speakers anyway I decided to set everything up hidden away. That left the dash hole, so I searched eBay to find an original radio delete plate. Since there were a bunch of dash styles and finishes over the years, there is a corresponding number of different delete plates made for these trucks, so make sure you get one that matches your dash grain. This one was labelled 73-77 and matches quite nicely.
Now I just need something to fill the tank switch hole...kill switch, taillight cutout...
