I had a '71 once that at one time had an AC system installed if you
can believe that.  Most of it had been removed by the time I bought
the van, and there were holes on each side, under the dash in some
metal ducts where the AC system had connected.  A *lot* of fresh air
came out of these when you moved the blue levers on the dash.  On my
'86 I see that air goes through a structural member from the center
behind the dash to the door area where it goes through those channels
in the doors to the B Pillars and on back.  (VW seems to like using
box shaped structures to carry ventilation air.)  I bet if you cut
holes in those you would get a lot of fresh air toward your feet.  I
would not cut them though because I want all the frontal crash
protection I can get.
