clutch fork and throwout bearing

just getting ready to install another transmission into my 86 b2000. how does the clutch fork attach to the throwout bearing? is there a wire clip or connector or does it just slip onto the throwout bearing without any clips. thanks. edsel...

The end of the fork slips round the throw out bearing then there is a little wire clip that allows it to lock onto the ball inside the bell housing.

so the wire clips to the round ball; but there are no clips where the fork attaches to the the throwout bearing. wonderful. thank you very much again. edsel...
