There was a group getting organized to buy some windshields through Steve Roberts, proprietor of SJSportscars in England about 2 years ago on the other group I mentioned. Maybe Peter was part of that deal. There was quite a lot of interest. I saw all the posts though, and they seemed to just come to an end. But maybe there was a new thread that I didn't see.
You could talk to Mr. Roberts, and see if anything is in the works wrt a shipment to the US.
Seems like windshields in the US are really a problem!
Good luck!
