I am making sure all my drains are correctly working and I am looking inside the panel from inside the car (from the left and right rear seat area with side panels removed) for the actual drains . Mine must be filled with undercoating as they are not clearly visible. Any ideas where they are or how many I should look for ? If I understand what I have read they funnel down to the rocker panel and out of the car ? Thank you.

On my 69 they're not very visible, they are on the side of a ledge not on on the floor, there is one in the front right behind the door jamb area and another in the rear by the wheel well. Feel along the ledge with your fingers toward the inside of the car.

They are nearly impossible to see looking down the window channel.

Thank's guys . Great photo dan that really shows me what I need. It seems to me if I insert a long skinny screwdriver through the matching drains in the rocker panel it should poke through the debris/undercoating on the 1/4 panel.

Your welcome. My rocker panels were packed full of mice nests. :eek:
