Final chapter (I hope): All set with new factory glass installed, looks like new, not 100% optically perfect (none are) but not nearly as distorted as the old one. Funny, it looks like the black border printed on the glass is a good deal wider on the passenger side than the driver's side, hadn't noticed that on the old one, but then I never looked. Windshield is certainly installed correctly as the little clear spot for the VIN is perfectly lined up and there isn't any wiggle room for the glass itself. I will have to look at another 5 to see if this is something out of the ordinary, but since it doesn't affect anything it's mostly just a curiosity and not a problem. If any of you notice this feature, I would be interested in hearing about it.
Service by Autex Mazda in Keene, NH. They have been fantastic and are very easy to deal with. They run their service department like a very good independent shop, lots of local folks bring other makes of cars (mostly upscale foreign - Audi, Mercedes, etc.) there for service. Glass work subbed out to a local pro glass shop that I have done business with before on other vehicles, they are the best around so no worries there.
