54GMC, just like the 12 volt native gauges for the '55.2-'59 GMCs are the same size and style as the '54-'55.1 gauges, I'm almost positive that the '55.2-'59 radios are the same size and shape as the '54-'55.1 units. They'll have the Blue Chip era GMC logo, but you can get a replacement face from any parts dealer. The Kook would know for certain on this.
