Andy, do you have access to the Slixx website??? Check under the "Goody Minis" category. They list several sheets, in both white and gold leaf, that contain only lettering to allow the builder to create their own class designation markings.... *PIC*
I used the letters found on on of their miscellaneous drag racing goodies sheets, to create the class designation markings, on this 56 Chevy Junior Stocker....
