[MBZ] need blower unit for 450sl

[The Wakin's]

Well, I have been fixing things on the new to me 1980 450sl. The blower
wasn't working at all, and I pulled it out today. It was seized tight, so I
put some PB Plaster on it and got it freed up, but it doesn't spin very easy
and when I tried it, it wouldn't work.
Is there a way to revive these unit, or does anyone have a used one they
want to part with (maybe Kaleb)?

Thanks
