Don -- We have a plan! We're not quite sure what it is, but we have a plan.

Also, to answer a few questions:
Why am I thinking it's a 49 and not a 54 (as titled...)? Well, to be honest, I don't know for sure -- I am assuming that the Chevrolet cues apply to the GMCs:
1.
Turn-down door handles 2.
single-piece windows 3.
Driver's side vent 4.
Series number on hood side Also, the "470" on the hood was our clue that the truck could be a 470...

Don't these cues together indicate a '49? Wouldn't the '54 have no side vent on the driver's side, vent windows in the doors, just "GMC" on the hood sides and push-button door handles?
Also, KB3CSW and I have a few more pics loaded
in the same place You can see some of the other trucks the gent owned who was selling the truck.
