yea...I know all about the 'fabric' ones that are all the rage. The ones that I've come in contact with are either difficult to store or crumple easy.
I also thought about the different sizes of windshields, but they aren't that much bigger now, and the rediculously long windshields of the 'cab forward' Chrysler years are over.
They are still made in China, and you can find random ones on Ebay, but have heard quite a few people mention the cardboard shades and how you can't buy them easily. There has to be a reason that they are gone.
