Rear defogger blower motor

I'm not sure if I'm breaking some rules or what but I've put up a couple of requests lately and the history seems to disappear. I've even had some conversations going and then the other members go invisible. I know we all may have spells where we're not on here for a while but I can't imagine going awol in the middle of a communication?

That said, I'm still looking to find the subject motor. I have the wiring and switch but the fan motor I had been using was a single speed and I'm interested in installing an original. Car is a 1972 Demon.
