I have some aftermarket sun-visors made out of the same material as the TT sq cab bottom windshields, I can mark one so you can cut it in the center and take out a very small amount, and cut off one mounting hole on each side and redrill and you will have a new bottom windshield frame, I've sold over a dozen and have a few more visors to make them out of, I don't weld tig, or mig, but it can be done easily 250.00 plus Insurance and UPS danuser88@ktis.net
