Inlet: In the Datsun 1200 passenger compartment ventilation system, air is drawn from:

the air intake on the cowl top, and
ventilator (quarter window) on the front door.

Outlet: This air is exhausted from the slip shape air outlets on the rear pillar (coupe air outlets are under the chrome side vents). Thus, the body is ventilated sufficiently -- even with all the windows rolled up.

The baffle causes water to run past the cabin air intake.
Carefully tighten the ABS plastic grille, not very tight, so that you do not crack the plastic.

Coupe

Coupe side vents cover the cabin airflow openings just aft of the doors. This allows positive ventilation of the passenger compartments, and the air exits at the vents.
