I got my new motor from Adventrure RV, it was an open box special but it was the right one. S110-464663 was what the invoice showed but this is the part, it is more expensive now. I did a quick search and PPL has it slightly cheaper but don't know about shipping or tax.
The job itself wasn't hard other then having to wrestle with the metal shroud and motor assembly. I took it off together to get the fan blade off. While I had it apart I did a thorough cleaning, blowing out the condenser and evaporator with compressed air and cleaning the outside fan blade with water and a brush when it was out. The one on the inside was cleanable with compressed air and I left it in place so I didn't have to completely dismantle the AC unit on top.
Here is a parts manual I was able to find for my AC units, yours may be different.
