Mysterious water leak, PLEASE HELP

[1970Turtle]

Hey everyone, every time it rains my floorboards get soaked. I figured it was the weatherstripping needing to be replaced and there is a small gap in the pass window where it doesn't meet up snug against the rear quarter window. However, I ruled both of those out after a monsoon we just had I went and checked the interior and the seats were bone dry, the rear floors and seats were just as dry but the drivers and pass front floors were soaked to the point water came up over my fingers when I pressed on the carpet. Is this something to do with the cowl rusted and leaking or what? I definitely want to fix this so I can patch the rusty front pans. It is currently raining and I went and sat in the car so I could see if it is leaking from anywhere. I pulled back the carpet a little on the passenger side and seen some water running down from who knows where. Not a lot, just a little but it isn't raining hard either. Any ideas? Thanks
