basically, you need to investigate the origin of the leak, we all have different issues, some are common due to the design of the body panels, but every vehicle will have aged a bit differently depending on where it was used.
after you dry the areas of concern, you can use a water hose and start a small flow of water at the base of the windshield by the edge of the fender and water for 10 min, or until water seepage shows in the cab... if none, move closer to the center of the windshield. Repeat on the other side. Also our door gasket called weatherstrip have deteriorated and water can finds it way between the door and the body frame along the A pillar... or simply from the window seal and leak at the bottom of the door and migrate from the lower weatherstrip to the cab floor.
As an update for my issues, floor is dry after the 2 big storms that we have in the last 10 days, and yes I cover the cowl intake with the plastic wings, which might be the best and easiest way to approach your problem
