Being a classic chevy enthusiast as well as an early Camaro enthusiast, the following statement jumped out at me (obviously in error as written) so I've edited in red to make it more correct.
"Supplier and non-GM OEM Tradenames
Glass supplier tradenames, like "Duplate," "Solex," "E-Z-Eye," and "SunShade" do not appear on GM OEM Camaro glass. Glass tradenames from other OEMs also obviously did not appear on GM glass. For example, "Safeguard," which is a tradename for Chrysler glass."
ie. Needs to be clarified that the statement only refers to CAMAROS since in the fifties, all GM tinted glass was coded 'E-Z-Eye'...
