I would have thought that more people would have had this problem. I looks at hundreds of pictures and all looks the same with the gasket inside the cutout part of the front windshield area of the cab or close to it. My gasket on the top will hit the wiper shaft when I open the windshield all the way open. I have found since I posted this topic that my frame has some areas the are wider than others and I also have some rusted out areas after I went back in and scrape the paint away in the track which causes the gasket to not seat all the way in the track. But it still sits crooked in the hole. Thanks Norm
