Repurposing the fresh air plenum, identifying options
I'm in the planning stage of installing a new A/C system in my '76 F-150 (standard cab) using a Vintage Air (Magnum) system. Going over the manuals which are available prior to purchase, I noted that the "fresh air" feature of the stock system will be deleted. The fresh air intake on the interior passenger side kick panel is to be blocked off. This seems to be typical of all the major aftermarket A/C systems.
This means that the slotted exterior fresh air intake between the windshield wipers and the plenum it feeds are now non-functional. So what are the options that folks should consider in the face of this situation along with their pros and cons. Some of the options that occur to me right away include:
cold air intake for the engine
fill the external fresh air intake for smoother look
rig a manual fresh air vent controlled by a push/pull cable or servo motor
forget about it, do nothing except block the cabin intake
I don't advocate this statement, but some famous words immediately came to mind...
Tommy Chong - "you could hide your weed in there, man."
On a more serious note - wouldn't it be an advantageous place to put something such as a ignition box or controller of some sort that you want to remain hidden?
Maybe an auxiliary fuse panel that swings/slides open?
I'm not sure how much moisture gets into that cavity, but something that requires "cooling" could certainly go in there.

Sounds like the old Dodge Darts where you could hide a whole six pack in the underdash fresh air vent!

Blocking the one entrance and two exits should make it a dry space.
You definitely want it to drain rain water, whatever you do. I'm liking the stealth cowl-induction idea, if it will work.
There is pressure at the windshield at speed. How best to capture it might entail some debate. Older cars and trucks (pre A/C) often had a manually operated scoop with a screen to fend off bugs and leaves. I can imagine one of those rising up on driver command at a stop light.
Would be cool if like on some of the new sports cars when at a certain speed the wing lifts in the rear, a cowl induction would automatically open at say 45mph and lower automatically at say 40mph. I'm sure that would take a little ingenuity and time, but would be cool.
If one were to do that should the two drains also be closed off? This would create a nice big dry space. Should this space be put to some innovative purpose other than a drug stash?
