Here is what I found on both sides of the car under the rear air vents. First thought it was a still, no such luck. Turns out it was a funnel screwed to the underside of the vent frame, to catch water and direct it out through the rocker panel by way of a rubber hose. Nice idea only wish they had the same idea up front in the cowl where the water rotted out my floor pans. Officially a Fred Flintstone mobile.
