Throwout bearing slipped off clutch fork

Working on a 69 charger 440 a833 that's been off the road for ages.. Had it all together and pushed on the clutch with my hand. Clutch pedal went almost to floor with my hand and I heard a loud noise. Then noticed the clutch fork was way loose to the point that I could pivot it rearward to almost hit the scattershield opening. Took it all apart and saw t.o.b. was hanging off fork by one clip. One clip looked way spread out so I used a vice to squash the clip back down where it's supposed to be. Put it all back together again and pretty much the same thing happened again (noise and clutch fork loose). Haven't taken it apart again yet. Thoughts?
