Aussie VC 67 Dodge ute
where the A pillar meets the upper plenum there's a joint. That joint has a tab the connects the upper and lower plenum creating a blockage to air flow up the A pillar as normally it's not needed because of the foot vent & heater. My new A pillar sections mate to the plenum cover and the A pillar is open to the plenum. Air can now flow up the A pillars and into the cabin creating flow through ventilation, all be it a small flow.
