[1978 T/A]

Ok guys, so I just removed my old blower motor this morning on my 69 GTO and the hampster wheel for the blower motor is rusty. Is there a replacement for this that I can pick up somewhere from an auto parts store?

I checked OReilly and they didn't have a part listed. I figure I can probably use the old one again, but I would prefer to replace it. I had another thought though. I am actually going to the powder coater today to drop off parts. Could I poweder coat the wheel?

One last question LOL. What do you guys use to seal in the new motor?
