I was catching up on some reading and stumbled onto this post about the Shat R Proof windshield. Years ago when I bought this Z I started paying attention to codes and the glass was the first. I learned that all the glass, LOF, is correct for my build except the windshield. I just thought since it wasn't LOF too, windshield wasn't OEM. Interestingly enough, my 69 06A final assembly date 6/6/69 Z28 has a Shat R Proof windshield. I'm the 6th owner and I have spoken to just about all P.O. except original owner in the 20 years I've had the car, and they all say the car has never been apart with a few paints over the original. Original vinyl top. All I do is drive it, maintain it, and correct whatever needs correcting. I took two pics today of the monogram. One looks like its double, but it's not.
