For those who have water leaking from dash...

This might be the problem with my 1970 Dodge Dart. Every time it rains I have water pooling on my passenger side floor board. I figured I had a bad windshield gasket. Never thought that it might be this. I'll look into this for sure. Thanks!

Pass side is not to bad to get to at all. It is the driver side that sucks big time.

One way to check it is to run a hose in to the vent under the windshield then get under the dash with a light and see what you can see.
