Hello All!
    Something that helped the wife's Cabriolet was a new ( I guess) light
that Wagner puts out.  It's called a 'Brite Light'.  They make it in all the
usual configurations, speaking of that, isn't the Vanagon a 6054 type bulb?
Anyone?  Anyways, this brite light has a Xenon bulb and also a different
lense configuration that allows more light to the sides.  The good news is
that it is cheap, no more than 15$ a light, and it is available/orderable at
most good parts outlets.  Also, it is DOT legal.

    Someone earlier was looking for heater parts, and some time ago I ran
across a German fella who rebuilds them.  Every time I call JB heater service
for info, no one answers (were talking years here).  His name is Ark Mirvis,
and he rebuilds heaters.  His telephone number is 973-398-6363.  If memory
serves, he is an engineer by day, and it took him many days to return my
phone call.  I hope this helps..........
