Every part of the new car comes from an Original Equipment Manufacturer, windshield included. The only two companies that manufactures their own glass are Ford and Chrysler. You have two options for a windshield replacement. First option is to select a replacement made by one of the various companies that manufacture OEM windshields. Second option would be to select a windshield made from non-oem manufacturer glass called Aftermarket Glass. Both OEM and Aftermarket auto glass must comply with the same Federal Motor Vehicle Safety Standard.
