hi, My truck seems to be leaking water into the cab and i cant figure out where.

When it rains, the carpet gets wet on both passenger and driver side. The water seems to pool close to the door, where the floor makes its transition from flat to angled up to the firewall. I have looked but cannot seem to locate where the water is comming from. The truck is parked outside and not being driven right now. Is there any common place for water to leak into the cab?

Its a 65 c20.



thanks
