All:
  This raises a question which I've been pondering since last winter, when
the rear heater alone saved my bacon -- in a blinding snowstorm, my
radiator clogged and the temp gauge spiked.  I cranked the rear heater
(my front heater blower is dead), the engine temp went down to
acceptable levels, and I made it to my destination not long thereafter.

  This year, I'm thinking about finally doing the dreaded front heater
blower / heater core dashboard massacre, but given the output of the
rear heater core and the cost of a new front heater core, has anyone
ever tried putting a rear core into the front heater box?  I realize it
would take some modification to get the rear heater core mounted in
there, but do I recall correctly that the black plastic portion on the
core which mates to the heater control valve is the same on both cores?

  Apologies if this has been asked and answered before.

Best,
d.
