I had many problems with the glass windshield on my Lister, most of which were due to how Beck designed the mounting. I finally gave up and went to using non-hard coated Polycarbonate (Lexan is a brand name). I got a 4'x8' sheet of Makrolon from Laird Plastics in downtown Phoenix for around $100 (cash only for small orders) but they will also sell smaller pieces if they are available. The hard coated polycarbonate is harder to come by and is much more expensive (3x I believe). As far as how scratch resistant un-coated polycarbonate is, it has not really been a problem for me yet and since I bought a whole sheet I can make another 4 windshields when it does. Coyled also uses non-hard coated Lexan in his Cobra and is also pretty happy with it. Another good thing about using polycarbonate is that you won't break it if you install it yourself, which you may have to do since I do not think that an auto glass shop would want the liability from installing something that is not DOT approved.
