Papa's CCPU,
The picture you posted doesn't allow me to see the length of the tube very well. The tube bracket riveted to your windshield flame looks correct, however it is possible that someone cut it off for some reason. Depending on how picky you are, if the tube was indeed cut off, a solution to the problem is to use a spring like a fellow did in the picture attached. I can measure the length of the tube on one of my windshields and post it here in Fordbarn if you want me to.
