1971 cutlasssupreme

So I replaced all weatherstripping on my 71 supreme when I did a repaint. Now for the life of me I can not get the driver or passenger windows to seal to the new roof weatherstrip. I have adjusted the window everyway but Sunday and finally got it down to only leaking in the 45 degree corner at the A piller and roof. Whats the trick to get this thing sealed back up? its driving me absolutely crazy! HELP!
