I was looking at how they open and close with vacuum and would rather just disconnect them, I have seen posts that seem divided if they even helped much anyway....

My 70 was air con but it was all removed way back. As Paul 74 said on the ac cars the rear vents for the astro ventilation are blanked off, I removed the blanking plate and just leave them open, every bit helps with the heat soak I figured. I also discovered this week that driving around with the rear window out but the t tops on works quite well:-)

Now bats, I think the flapper doors are normally closed, and the vacuum opens them... so if you just left them they should be closed. A new gasket set was only about ten bucks.
iwasme....when we tore into our car for the rebuild, the plenum was full of leaves, dirt, and sticks. After paint, I glued black fiberglass window screen on the bottom of the vents to help keep it a little cleaner. If you didn`t know it was there, you`d never notice it.....

Nice
I have a coupe, and I`m not planning to close mine.... in fact I`m playing with the idea of an electric operation, maybe with something like a door lock or window motor.

My car was originally a non-AC car. But back in the day when it was my daily driver the hole would get plugged then fill up w/ water and get it the car. I siliconed mine and screwed them shut- and added vintage air.

Not trying to give purists stomach cramps on this one but I am doing something of a road race old school look,
I want remote jumper lugs on the rear and one of the big flaming rivers style kill switches, well I saw a picture of a racer that had the kill switch in the driver side rear deck vent, I can't see how it's mounted but thats a great close to battery location thats easy to get at.....

I have a non-A/C coupe and the vents work very well.
When driving in the fall, in a slight rain, they pull a nice flow of air out the rear with the windows up and the tops on. I have also never had an issue with plugging of the drains, etc. I'd say keep them if they work!

My coup came with A/C and these things are just dirt collectors. When I wash the car, they always produce a water trail down the deck after I have dried the car off.
I'm going to look for some chrome plates ones now. Mine are black and always look dirty.
