Nope, they reinstalled my old glass. Actually, the guy that showed up was the same guy that took the windshield out 3 years ago. He wondered why it took so long for the reinstall appointment.
He was very familiar with the old cars. He mentioned that by law nowadays, they can only use the urethane sealer and not the old style butyl rubber tape from the old days. He said that is because the butyl will heat up in the sun and the window can shift...it can also pop out/blow out in an accident. The new urethane stuff is pretty close to permanent and if your windshield is installed with it and has to come out later, it will definitely break during the process. (They had no problem taking my old one out 3 years ago because it was mounted with the butyl tape)
He had some neat hardware on his rig - such as a urethane heater that the tubes sit in and get warmed to 175 degrees, and an electric cauking gun that allows him to put out one continious bead without gaps of clumps. Very interesting to watch.
It was Diamond Autoglass (now Safelite) in Flemington. They charged me $50 per window ($107 total with tax) and even showed up an hour early. Good people and very meticulous.
