Mcmaster Carr clutch lining may work.

iif you have a shop that relines brakes and clutches in your area you might check with them.  Toro still sell new clutch disk, but a bit pricey.  You might also check with A-Z tractor in the vendors section here for a used one.

good Luck, and let us know what you find that works.
