Cab Leaks 84 W-150

If you have noticed any of my posts 1) I am new to the forums 2) I have purchased a 1984 W-150 to tinker with and turn into a reliable farm/hunting truck. I have been attempting to get the interior dry and have been making progress. I stopped most of my water intrusion by replacing the door weather stripping (both sides) purchased from JC Whitney (installed easily, works great). Had the sliding back glass removed and replaced with solid pane (have not noticed ay leaking there since). I also had the front glass removed new gasket installed and resealed. The front windshield is still leaking between the window and the rubber on the inside lower corner drivers side. I am also getting water from the vent area on the drivers side down by the parking brake. Has anybody experienced either of these problems and/or have any sure fire fixes? I have already removed all the floormat insulation once and undercoated all of the interior floorboards and hate to keep removing the stuff to get it dried out. Appreciate any ideas/comments on these problems.
