Ammeter to Voltmeter...who does it?

I'm looking for a white face sticker for my plymouth radio now....anyone know where that may be located?

That's another one of the many short comings of the aftermarket.
If it helps... Most any print shop can scan your original, invert the colors and print it. High cost comes in custom work, the quality of material used, count printed per sheet, cutting to exact size, etc..
If I only wanted the one, I would approach those guys that make custom front plates at my local flea market.
