Lost 3/4 of clutch peddle

I don't have a pivot spring. On the clutch fork there is a tab that slides into a bracket that is mounted to the scattershield... that's where my clutch fork pivots. The pressure plate and a return spring keeps it all togther.

I would find out why it came apart in the first place instead of re-installing everything and most likely come apart again.... much less cut or modify something. The reason I say this is because it worked for a while like it is intended but then something gave up.... whatever gave up needs addressed wouldn't think?
