Got the heater working.
BEAUTIFUL weather today, figured, hey, couple hours and I'll go for a ride.
Um... yeah, five hours later, including a quick trip to ACE hdwr for new rubber grommets and some hose clamps (went ahead and replaced all the 5/8 hose while I was doing it), replacing the motor (the original intent as the sealed unit was toast), the air intake plenum/big rubber thing, flushing the heater core (which I'll do again formally in a few days as I intend to run some prestone flush in the system, drain it, and replace all the other hoses), and replacing the 3" pipe from the fan housing to the exchange unit (or whatever it's called)...
WOW does this throw out a lot of heat. But it was also around 55

But as long as the weather's nice, I just might rebuild the steering wheel lock (ACE has cable, aluminum pieces, I have a swaging tool), replace the steering wheel shaft boot, put dynamat insulation on the driver's side firewall, replace the little plastic doo-dads inside the gas pedal bracket so it's more solid/less wobbly, and...
so it goes.
