Hi fends, and a warm welcome to the forum. grin
It's always great to have another Scott Bonnar owner on board. wink
You have received the correct advice; parts for the Model 40 are very thin on the ground, however I will send you a private message (PM) I may be able to help you source the clutch part you require.
Just have a look for the flashing envelope next to 'My Stuff' in the top toolbar and have a look in 'My Messages'

Once again fends, :welcome: to OutdoorKing
