wilbur - thanks for the tip that the 54's are available too, I didn't know if the volume for them had warranted PPG's interest!
hadn't thought about Pilkington doing windshields, but I guess they'd be as big in auto glass as PPG? not really current as it's been 20 years since I was really involved, and only in architectural glass
you're the one who should get up a tech tip on the glass for these ol rigs, get folks in touch w/ using their locals for glass needs
