More importantly, can you see the clutch release lever on the transmission side move when your helper pushes down the clutch pedal? And does it stay there when helper just holds the pedal down?
I can't remember exactly: what was the symptom that caused you to replace those? Was it the pedal OK, then occasionally not coming back up? If so, issue not inside the bell housing, anything wrong in there will not temporarily seem OK.
