I originally wrote: --------- What's a "grille, body lock pillar exhaust" good for? Apparently not much, as it was discontinued by 76.
The 74 has 'em (pic 1
and pic 2 : part type 23-36-55
, and the 76 doesn't (pic 3).
It looks like the back of the grille has many one-way valves to allow air to flow from behind the grille to in front of the grille (pic 4).
I traced the air source up by the sail panel (pics 5, 6, 7).
I guess a better question is "what possible problem was this grille system designed to solve"? Allowing air to travel from the sail panel down to the rear of the door doesn't seem like it would be particularly useful. ---------
