Window glass.

But doesn't all auto glass have to meet strict government standards for safety????
Only when they make the car. If the window gets broke see if your insurance will pay for a factory glass. No they won't, Only glass that meets the replacement requirements. I wanted to have my windshield on my new truck replaced at the Dealer so it had the mopar star. They wouldn't do it they called in a glass shop to the body shop. The insurance had them right on the estimate. They wouldn't even install a used windshield because the prep would cost more.
