Body Colored License Plates for GM C8 Show Cars

[Classic-Chevy-Guy]

Most of the C8 show cars have a body-colored license plate and not a Michigan one.

Yet the body-colored license plates seem to be a unique set of numbers and letters.

Do the numbers and letters mean anything special, or is it just how GM identifies the car?

I don't see it. Are you talking about the indents in the license plate area when no plate is installed on the rear?

Don't know if they mean anything, but they aren't legal plates, and those cars can't be driven on the street with them. They are trucked everywhere.

Yea. No idea. My first guess is its a fleet number of some kind. Maybe for the cars on tour.
