Magilla: A word of caution on that radio that '54 GMC linked...it's a Chevy truck radio and will not fit your GMC. BUT! There is another trick which I have kept in close confidence and will now reveal only to the stovebolt nation: '55-'59 radios will fit the '54 dash. They are not all 6v + ground like the 54 is, but the radio will fit and look right and you can have it rebuilt to whatever your truck is.
Magilla, that is a great truck you got there and it would sure be nice to do a mechanical only resto on it and drive it just the way it is. It is an ULTRA RARE unmolested original '54 Deluxe cab truck from what I can see of it.
The '54 Chevy truck radio will not work. The '53 Chevy CAR radio will work, but you will need a GMC lens and square bezel for it to look right and fit the dash opening. The oval bezel on the '53 Chevy car will not make it through the '54 GMC dash's stock radio bezel opening.
