Maybe not the exact same thing but the price is right and they sure look like they would work ok to me.
This is the size I need for the drop stand for my old Elgin, but there are all different sizes.

Those could be a way cheap alternative to the real deal, the key is the length of the shoulder so the drop stand doesn't slop around too much.

I'm thinking a washer that will also act as a type of bushing between the stand and the frame.
Mayhaps brass or bronze.

Could work.
