To eliminate the TOB discussion, just back off the preload on the clutch fork and pull it away from the pressure plate.
Not knowing what is in there for a TOB, I'll offer this. Many of the TOB's provided in clutch kits are not a very good quality piece. Many are plastic. There happens to be one in my 71 Trans Am and it makes noise (albeit I can change it by playing with the clutch pedal).
I will be changing the TOB in my TA (and any other clutch job I do) with this.....

By what you have shared, I don't know if that is indeed your problem. Is there a forum member that is close to you? Speaking for myself, when I get frustrated I get my head spinning. Sometimes a fresh mind, ears, and set of eyes is the best way to solve a problem.
