Well guys, I just picked up my vette and I'm happy with the job. They had my car in the shop at 8:30am and did not back it out until 2:30pm just before I picked it up.
I'm attaching pictures of the original glass and replacement glass labelling.
It turns out that they were both made at the same plant:
AP Technoglass Corp. in Bellefontaine Ohio, USA.
The cash price quoted for HUD glass was $1100 but this was by phone and they did not know about my OnStar/GPS antenna box. The glass that arrived was not correct not having the additional necessary connections.
The correct glass installed today would be $1400. Some of you have mentioned finding lower prices so this may not be the best possible deal. I'm not worried about this one as I had only to pay my $50 deductible.
I would say that this Crystal Glass
location came through with the proper amount of care, attention to detail and fussiness that we Corvette owners expect!
