'65 Barracuda Interior moldings under rear window

I'm scratching my head. If the holes are covered with a solid plug, how do you get flow through ventilation?

I can tell you there was never an intended vent in this location on my Barracuda. Nothing when the rear bulkhead is closed. There are some elongated slots inside this frame channel you can feel thru the rear rubber flaps. They are not exposed to the interior however.

The plastic plugs I referred to are simply covering the required access holes to mount the exterior rear center molding.
