Where can I get Huffy lawnmower parts?

1969 - 1974 Huffy Sheraton or Caprice. Looking for mower junkyards or anyone willing to sell the unique blade pulley. (see pic) I think these direct drive pulleys were only made for Huffys, maybe some MTD's and Craftsman riding mowers. I welded the pulley back together 5 years ago. Worked OK, but last year, it was burning thru belts and just vibrating way too much which is probably ruining the engine. I found 2 junkyards, but they weren't very helpful and won't ship. Within 2 hours of Cleveland, OH would be awesome, but I'll take any junkyard in the world willing to sell me this pulley

The reason you are burning up belts is the adjusting bolt has fallen out ( top left in your photo )
This has allowed the guard over the top pulley to run on the middle pulley and the belts to rub where they should not be running.
I am no huffy experts but can see the whole blade engagement set up is wrong.
Hopefully an owner can provide you with a picture of the correct set up for the pulley & belts.
You can clearly see how the top pulley used to pivot, away from the middle pulley not towards it.
