Original windshield?
 

I may have removed what was the original windshield from this 67 swb the other day? The glass is completely clear. No tint or shade. If it had been replaced over the years I'd guess a shaded and/or tinted windshield would have been used. Also, the gasket was stiff as a board and the original vermillion red was under the gasket. Most significant I think is the thickness of the glass. More than 1/4" and very heavy.

From a Camaro site, markings would indicate an October 1966 date code.
