Finally got junkyeard motor into my blower. following cautions: 1) Be sure to remove small screw (s) from firewall side from Resistance plug. No DIY instructions advise this, and if not done will cause pigtail plug to break. (found this the hard way even after lots of research). Most plastic housing from original cars are age rotten! Be sure replacement housing is free from cracks and missing parts. I salvaged and used epoxy where ever needed, and frankly although everyhing is working NOW, I dont have much faith in longevity. Good luck to all, Abe g
