I don't know about the newer glass coming out of Maier. But a couple of years ago now, I picked up a front clip, both fenders, racing apron and front spoiler (one piece) and a shelby hood. The guy that I bought them from told me he had purchased them in '76. They are still in great shape, except for a couple of fixes here and here and alot of old paint to remove.
