Where is the freakin water coming from ???

windshield gasket is also a common place for water to leak in, like 69mope mentioned

I'm pulling the windshield out of my '74 for that reason. I always thought my wiper seals or cowl drains were the culprit. Nope, I happened to be at the car wash and saw it come in around the top and bottom corners of my windshield.
