Small Engines (Lawn Mowers, etc.): MTD obsolete snowblower parts, mtd snowblower, ebay

Question
Hello.
I have an old MTD snowblower by Mastercraft (~1979).
Model no. 319-825-515
I need a blower fan assembly.
Part no. 05812-0637.
It appears that this is the only part not available anymore!
It also appears that this design was built for about 20 years (1977-1997?).
Branding includes Troybilt, Cubcadet, White, Craftsman, SnoFlite and others.
Where can I get a replacement blower for what appears to be a common older machine?
Thank you.

Answer
As you mentioned the part is no longer available.  I checked Ebay, very few Mastercraft parts.

The site below states the part is compatable with several neew models.  Check the link to see if the part will fit.

What is wrong with your fan?
