I have rain water leaking into the cab on my 79. Both driver and pass sides. Dripping from under the dash. After searching this site it looks like a common problem with the 93-94s. First thing that I plan on doing is having a new windshield seal installed. I have owned her for 23 years so I think I own her that much. I guess I need to if I should follow the same advise as the 93-94 guys or is a 79 differnt.
Thanks

 

A 79 uses a rubber gasket to mount the windshield, the newer trucks have a glued in type, but if your getting leaking from the dash my guess would be the windshield. I've owned to 79 F-150's and I know that the rubber winshield seal gets old and cracks, so after this many years of good service I think a new gasket would be a well deserved treat for the bronco, as well as the likely culprit for the leaking.
