I've got a lot of rust through on the cab around where the windshield would be. Some of the holes, as I was told on here before, are probably from the urine of mice that may have climbed up into the cab roof. I'm really not sure exactly how to shape the metal to rebuild this area. If I buy new inner and outer roof panels will they have the correct bends to complete the area where the windshield gasket goes? Has anyone rebuilt this area to use modern winshield adhesives instead of the gasket like it is on the modern trucks?
