If someone hasn't already said this...the front clip is definately '54. The cab is the earlier style, with the exception of the steering wheel and horn button, which are '54. The bed is the earlier model. I'm guessing the frame is the earlier style, too. What engine was in it? 216 or 235?
From what I've heard, I'll go with the idea that it is a '54, but for practical purposes, a lot of those parts are '53 by American standards.
The '54 style grille looks great in chrome - check the Gallery, there are several examples there.
