Thanks Steve. So much to learn, even about glass. Yes, I am seeing most of the cars here in the US with green tint. The glass I have in my car, which seems to be original, is Dura Glas, which is written in white font. The new glass from the dealer is black font. The problem is they are currently out of one of the pieces I need. The windshield in the car says Alpine Glass. Just wondering if anyone knows if Alpine Glass was an original supplier for BMW? Looks like I am going to have to go with a new full set. There have been a lot of good ideas and suggestions here from everyone, so, thank you.
