Firewall/Under Dash Water Leaks

Have you checked the windshield wiper pivot seals???

Those get old and shrink allowing water to get inside the car....
I did mine. Still leaked. Need to do the windshield. Looks like a pain in the ***, as I've read you have to have the clips in and the trim to make sure it's fitted right. And my trim is missing... think my Bro I got the car from lost it
