I replaced my broken glass windshield with a poly unit from Cobra Valley. It is very clear, doesnt seem to chip (has sustained some scary impacts without marks let alone breaks)...A bit pricey.
They can custom cut them.

Did it myself with the help of a competent friend, not too bad: left the uprights in just removed the frame from the uprights...
