I did pretty much as Harold stated to create the CHEVROLET vinyl decal for the dash in my '54 3104.
I scanned a hood decal, then PhotoShopped to make the right size for the dash. Took the file to a vinyl sigh shop near my house. The shop created the decals fast and at reasonable price. NOTE: the price varies greatly between shops.
> '54 Dash <You won't need to do any PhotoShop magic, since you won't change the size.
Tip: Use the rubber eraser end of a wooden pencil to press the letters into the indention of the grille to remove air bubbles.
