You can buy a "hidden radio" that you can mount practically anywhere, even under your seat.
You will need to buy a 6 Volt to 12 Volt converter if your truck is 6 volts.
It comes with a battery operated remote control and BT built-in to the unit.
I suppose you could link it to your SMID (social media insanity device) but I wouldn't do it.
These old trucks need both hands on the steering wheel and eyes looking out the windshield.

"Adding CFM to a truck will only help at engine speeds you don't want to use."
"I found there was nothing to gain beyond 400 CFM."
