Craigslist ad had some original 69 camaro glass, so I called and asked for a picture of the etching. NV could either be Jan 69 or Jan 82. I could have been fooled with the date code NV if I didn't read this "Glass supplier tradenames, like "Duplate," "Solex," "E-Z-Eye," and "SunShade" do not appear on GM OEM glass. ".
