Desperately needed: centrifugal clutch parts!

My motor kit came with a centrifugal clutch. If anybody has one like mine, and you have some spare parts lying around, I need to get some parts to repair my clutch.

Attached are a couple photos showing what I need. Please let me know if you might have this stuff lying around.

The part circled in red is the part that broke. The second photo is a closeup of that part.
