i used vintage air genII compac system, did not like the look of the sure-fit system's plastic stuff.
the va unit sticks out under the dash quite a bit, i put one vent in the kick
a 4'' fascia covers the va unit
and the other vent is in the steering column cover
without the console this would have been a nice finish to any dash.
you could make a one piece fascia all across the underside of the dash.
