Wouldn't the EX plate be seperate "if" the car started life as a production model, such as the early Corvettes with Engineering or Styling EX numbers? Was that the same OP during the C4 era or would a "Rev number" follow the car once ISO became the norm?

I worked in the GM system with Delphi, Magnequench and Guide Divisions for several years during the 90's and 00's. Once ISO became a way of life, Rev #'s followed any deviation from the norm.
