I found this on the glasslinks site in the technical section.

All Guardian automotive glass products sold in North America are manufactured in the United States by the same conscientious, dedicated American workers at the same state-of-the-art U.S. facilities to the same exacting standards as the products that Guardian sends to the assembly plants. While it is not true for every OE glass manufacturer, if it came from Guardian, it is absolutely OE quality every time, regardless of what you call it.
