i FINALLY have located Clim Air, the German company who makes the vent shades/
air deflectors for the vanagon..  they are also the same company who made the
sunroof bubble air deflectors...
i just got a pair for my front windows, and they just arrived, today...i was
really impressed, they are made quite well. they were $45 a pair, and the ones
i got were smoked tint.
