Throw out bearing question

additional to tonysrt.....
Is this a setup that has worked previously for you?
Do you know the parts are correct?
Fork tips and pivot not bent or worn down on an angle?
Is the fork all the way on the pivot correctly?
Release bearing retainer clips bent, too loose and just won't hold?
Is too much pedal travel allowing the clips to slide of the fork tip?
Cracked bearing retainer tube?
This is a new set up to me correct part number bell housing for a 70 abody clutch fork and pivot are correct 12 1/2 long (two hump looking pivot) not sure how else to describe it. Clutch pressure plate and flywheel I bought together 3 finger style the bearing came with clutch but not in a box it’s new but I have no idea if it’s correct also I don’t have an over center spring not sure if that could affect it. I don’t mind the stiff pedal but not sure if it needed. Bearing retainer is good no cracks.
