I had the same problem on a smaller scale. I need a corner section for my 3807 flybridge windshield, and neither Carver nor Taylor Industries, the manufacturer, has it or the pattern. Taylor referred me to Ocean Dynamics, in Miami, Fl. (518-773-9226). Ocean Dynamics will custom make my part for $357. I guess it could be worse, but I don't know what a full windshield might be. Of course, if you are not needing an exact replacement, there are any number of windshield fabricators that might make a less expensive generic replacement.
