Al,
Nice job on the heater distribution molding.  I take it that the entire unit
sits in the cabin area so that only cabin air is being heated by the heater
core.

What is the size of the heater core (dimensions), and what is the weight of
the blower motor?

Do you find that you need to destroy the mold to get the part off?

Are you planning separate ducts to windshield, etc? if so, what are you using
for the control of the air flow -- I have found normal "heat boxes" to be
very expensive from Aircraft spruce, etc.
