Biohazard
Before installing the blower motor, I decided to put 12 volts to it again and listen to it run. Seemed to have a slight squeak but otherwise, no issues. Still, on a whim, I split the motor body and pulled the rotor just to lube the end of the shaft. After wrestling it back together, test-drive results were: no squeak and, the longer I kept power to it, the faster it ran.
Couple of things you may notice: The plate at the evaporator ports got painted black on the cabin side (you can see the paint on the edges). I also painted one of the vacuum diaphragm mounts. You can't see this stuff once installed - it was really just for rust control. I also cut thin strips of roof flashing to seal up the box halves around the blower. I used it only on the firewall side so it won't be noticed from the cabin.
