If you're cheap, a Rabbit front heater core can be made to serve as a Vanagon
rear heater core.  The last one I got was brass - should last forever.  You
lose the shut off valve in this deal but you can get an inline shutoff valve
from a Rabbit that works nicely.  I turn my rear heater on once a year and
off once a year, so lifting the seat and turning the valve by hand is not a
big deal.  By the way, you have to trim the plastic heater cover to make the
new core fit.  Not pretty, but it works.
