There are a couple seams where the cab was pieced together that the seam sealer dries up and cracks, that always leak. They are located under the Cowl and are about 6 inches in from each side. There also are seams above the windshield at the same locations that are prone to leaking. Using Black RTV in a caulk gun to seal around the windshield gasket (inside and outside) helps as well. But truthfully, this is only temperary and sooner or later you need to pull the windsheild and fix the seams and install a new gasket.
