Trunk Lettering 1966 Barracuda

Hi everyone out there in Mopar land. I need some help with my1966 Barracuda restoration. I am restoring a 1966 Barracuda Formula S number matching 4 speed beauty. Can anyone tell me if any 1966 Barracudas came with no lettering on trunk lid. The 1966 factory broacher of the car shows pictures of car with no PLYMOUTH lettering on trunk lid. The trunk lid that was on car when I purchased it had no lettering. Is it possible that some early 1966 Barracudas came without lettering.
Thanks
