I can't find it right now but one of the major manufacturers has an nos or classic car locating service for glass. They basically keep a log of all the old stuff in their distribution centers. My 66 dart had a clear windshield. The reproductions had the blue tinted stripe at the top and I hated the look. They found 2 NOS clear windshields for me. Of course the first one was broken in shipping....Second one made it and honestly, it is one of the best "details" I did for the car. Not cheap but it was worth it !
