Hello, I’ve started the restoration of my 1970 RS/SS, which has a tall rear spoiler. When I removed the center spoiler section, I found the mounting holes for the “Camaro by Chevrolet” emblem beneath. Does anyone know if the factory drilled the emblem mounting holes on all cars? (which would just be covered by those that were spoiler equipped) And last, was the emblem ever installed on tall spoiler cars? My car was built in LA (June - 70). Thanks in advance!
