Hi TC,

I've never heard of a front heater core developing a leak.  The rear
core is another story, though.

The blower motor on my '84 works fine and the one on my '85 should last
through another winter.  When I replace that motor, I'll regasket the
flaps on the heater box but I'll leave the existing core in there.

You can extend the life of the blower motor by remembering to turn off
the fan once you're up to speed.  The incoming fresh air is such that
you won't even notice that the fan is off.
