There's a good picture of the '54 radio/dash on the Golden State Parts catalog site (far left).

I have a similar problem, buying a '55 eBay car radio for a mere $26 to drop into my '54 GMC. I think the trim plate will hide a hacked dash where the PO installed a nasty radio in the '70's. Although the years don't match, I like the look and may opt add modern components to the face. Not sure where the speakers will finally end up.

TC-sorry someone from my part of the world has done you wrong. We're not all bad!
