Any idea where I can find this part?

That's the Z bar, but I don't understand how that could cause what you described.

I could understand a throwout bearing arm folding in half.

Doesnt look like anything wrong that z bar ,I would check to see if the clutch fork bracket in the bell broke or the fork folded . I doubt theres anything wrong with that z bar

One of the arms is broke off the Z bar.
