Water leak inside 65 barracuda

On all but 1 of the 6 A-bodies I have owned they all leaked in various ways. wipers, cowls, windshield all are to blame. What helped me on the 63 Valiant was to take some screening rubber (I think it is called the spline) and run it in the windshield channel. It works great and being black looks almost stock. hoping I am not jinxing it now. I still keep a pan down there at night in case of failure.
