'69 gill slits question
Can someone explain why some of the '69s I've seen have the rearmost gill slits blocked off? It looks so much better when all 4 on each side are open. I understand the chromed inserts were an option, but what's with blocking slit #4? Thanks! —Mark

Actually, all the '68-69 rear gills come blocked off stock. If its open, thats the one thats been modified.
What you see is an optical illusion. If the rear gill is painted black to "blackout" the gill, it looks open. Cars with the polished louvers in '69 and the back gill painted black look open. They arent.

Okay, thanks. But WHY is that one blocked off to begin with? And the ones I'm thinking of were not painted black to simulate being open, but were actually open. So you're saying someone cut into something to open that last slit up?

That area of the fender, is where the cowl is closed up, to create a plenum for outside fresh air, to be fed to the interior. Air is drawn in at the base of the windshield, down through the plenum formed in the cowl, and out through the vent ***** in the dash.
The first three vents are open, to vent hot air out from under the hood. If that forth vent is open, it will draw the hot under hood air and fumes, from the other three vents, into the interior.

Hi,
In rvzio's thread "rvzio's 69 restore" (on this page) there's a picture of the gill openings taken from the inside of the fender so you can see why the last gill can't be open.

Alan

At the factory, the rear 'gill' was given a "blackout" treatment with some satin black paint....so that it would appear to be open. What "Bubba" does when he gets hold of it, I couldn't say....

If you open the last gill the opening is in the hinge pillar air plenum as gb explained.

The rear area of the 70-72 side grill opening is blocked off for the SAME reason.

Here is why you should not cut open the rear gill. The vent door for the interior kick panels is right there.
