>> Most of the 1 DIN Chassis size radio sold at Wal-Mart will fit just fine in the GMC radio hole. You will need to bend the sheet metal ears, and trim the dash. Wal-Mart also has a wire adapter kit for that era GMC vehicles. Once the radio face plate is added to the radio, you have covered your adaption to the dash. Run an anchoring strap from the back of the radio mount to the vehicle chassis. Stop the radio from vibration.
>> Early GMC's used a common ground return for the speakers. I think the change over was during the 1977 model run. No idea at which TZE number. This will kill a modern radio. You can get a adapter that will handle this, from Cruthfield, or run new wires to your speaker system. Running the wires up front is not difficult, but the rear might be interesting.
>> Some of the radios that are at Wal-Mart, as well as other suppliers, have remote controls. Velcro to steering wheel or top of dash for easy radio operation.
>> Since my GMC has two batteries up front, I run all accessories from the house battery, rather than the engine battery. They are wired thru a separate fuse block. I can run the radio without worry of draining the engine battery.
