I'm currently replacing door locks, side mirrors and wipers and the truck will be 99.5% complete.

From the prior post re: the heater repair. Unlike the Chevy C10, the GMC has a single heater control knob that requires pulling out from the dash to open the outside air flapper valve and twisting of the knob to turn on the blower. So, doh, operator error on my part - the heater works just fine.
