Clutch pedal just went almost to floor before engagement

Z bar was fine. The linkage rod (which pushes against the shift fork)with the threaded nut was super loose. The rod threads are not in the best shape, but I tightened up the nut and it seemed fine. Worked the clutch pedal a dozen or so times seems fine, so took car for a spin, everything seems normal. So for now I’ll call it good, but I’ll be ordering a linkage rod to replace mine which isn’t in the best shape. Still not exactly sure what went wrong. Throw out bearing is fine, clutch fork looks straight, pivot under the clutch fork didn’t feel damaged (can’t really see it but I felt around with my fingers to see if it snapped, cracked, bent). Clutch pedal looks fine as well as the rod that links the pedal to the z bar. I’ll keep it on my radar and see how it goes.
