I don't know where you live, but around where I live there is no such thing as a English specialist when it comes to auto glass. I suggest that you contact a good glass shop and see what they can do for you. Keep in mind that you can get a replacement glass at The Roadster Factory and at Moss Motors. Then once you have it in hand go to a glass shop to have them install it. I need a new glass in the TR4 that I am working on. I plan to do the latter when I am ready. I believe that TRF has tinted windshields, which is what I want.
