When you redo the windshield, be sure the windshield regulator causes the window to hit the two rubber bumpers near the middle of the window. If the frame hits at the corners, you may break the glass when closing the window tightly. At the extreme ends of the windshield frame, there is enough leverage to break the glass. If you are missing the bumpers or they are deteriorated, you can purchase new ones at the usual vendors, like Jim Carter. I have a factory technical bulletin from 1937 that explains this and it would apply up to 1946.
