I posted sometime ago about having a water leak coming from the top of the a-pillars due to rust, so today I pulled out the carpet to find it has been leaking longer than I thought. When I got the truck 2 years ago I had pulled the carpet out because it was full of mud to find the drivers side had a hole rotted in the floor, passenger side was ok still looked new. Today the passenger side is rusted also, so I decided to see whats going on by putting a small sprinkler on top of the cab and getting inside to see whats leaking. The drivers side above the parking brake pedal is dripping, and passenger side somewhere behind the dash behind the foam padding. I thought it might be running down the a-pillars but I ran water just at the bottom of the windshield and cowl area and still got a small drip.

So if you managed to read all this I have 2 questions, how tough is it to pull the dash out and is there any known rust areas like at a seam or someplace?
