I think I would like to delete the louvered area behind the rear windshield of my 73. Do not think I want water hoses running through my interior. Opinions? Thanks Guys
I have the rear vents open permanently to help with interior ventilation, the drain hoses were perished so I replaced them with flexible electrical conduit instead of the rubber replica pipes, it was a lot cheaper and will last a lot longer. If you don't use the vents I can't see any reason why you couldn't delete them if that is your preference, I quite like the detail they add to that area of the body.

I do not think there is a ventilation effect with this. It looks to me like it just takes water that might accumulate behind the rear glass, and allows it to drain behind the rear tires. Am I missing something? Interesting thought on the detail it adds to that area. Thanks for the input.
this is your astro-ventilation. the vent there is for ventilation pass thru that is open when your temp is set to cold. it just so happens that the vent will collect water when it rains and that water needs to flow out. I am sure there is a wind-tunnel-buffeting theory for the reasoning of this system. closing it off may give you unintended effects.
Hi Frank,
First off, does your car have a/c?
If it does the vents are closed off at the interior of the car (but not the drains).
If your car doesn't have a/c then the vents are part of the astro ventilation system as jw described.
To remove the grills and fill the rear deck, or simply block the flow of air under the grills, would likely be more difficult and more costly then replacing the 2 hoses (if they even need to be replaced, and they rarely do.)
So pour some water through each grill and look for leaks in the interior.
If you don't see any you're done!
Regards,
Alan

The hoses only carry away water (rain, car wash, etc). Have you had a leak? You could crawl underneath and disconnect the plenum end of the hoses. Water will still drain but not through the body.

Hi Alan, yes the car is factory AC. I guess I will just put in new hoses. I had pulled the original ones that were toast. I closed off the drain ports in the wheel well planning on deleting the drains. Will be easy to open them back up. Thanks for the input sir!
I just replaced mine a few weeks ago. It's not too bad and requires a drill and a rivet gun assuming your wheel well plates aren't too rusted. Mine looked OK, but upon looking closer they were well rotted. The end of the tube is actually a flange gasket that sits under the round drain port.

Another idea for the vents is to epoxy some fiberglass window screen to the bottom of the vent trims to help keep leaves & dirt out of the plenum area too.
