I have had this problem for YEARS! Water seeping into the cab. So I always try and park facing downhill!! Usually works. And finally after all these years, I am getting around to doing something about it. The water comes in from the upper left corner of the dash, body seams leaking it appears. I have sealed and resealed the windshield many a time! I have also removed the dash, cluster, turned on the garden hose and soaked the hell out of the area to try a pinpoint the exact leak to no avail. I order from LMCtruck.com, a pair of fender seals and hood hinge deflector seals and it's a big job to install them. Involves removing the fenders, hood, cowl, inner wheel wells, etc... Anyone else have a similar problem? How did you solve it? When I remove the fenders, any areas I should be checking and welding or will these fender seals do the job? Thanks!
