re: #203 O say, does that Star Spangled Banner yet wave..

Straight swapping of the motor doesn’t look to be that big of a deal. I have the blower unit dropped out of the furnace; that was the easy part, two screws and it just slides out. I need to snap a couple of pictures of all the wires to make sure I get them all back on correctly, then unplug/disconnect everything, haul the unit out of the furnace, and then the swap is pretty simple. Unhook the motor, separate it from the blower fan, installation is the reverse of removal.

sounds good.
good on you getting a head start on it.
