And just to expand on this a little, to help you or anyone else who may read this, there's a couple factors that can cause this part to break, in my opinion.
One, its a weak, poorly designed part. It should have metal running the full length, up to and around the eye.
Two, when slave cylinders go bad, which is almost guaranteed in this transmission, and then causing great difficulty shifting into gear, this pushrod pays the price and bears the brunt of the driver wanting to push the clutch in further than it can go try to get it into gear, leading to the part eventually breaking as shown.
And, less common but worth mentioning, the clutch pedal pivot point will wear from extra force on the pedal beacause of the bad slave, and develop slop in the pedal movement. That translates into less clutch engagement, making it even harder to shift!
You may not have any of these other problems, but it's worth knowing about, and watching for.
