check the pedal pivot bushing way up at the top of the clutch pedal. and DEFINITLY check right in the middle top of the clutch pedal where the spring actually sits in (the slot with the plastic insert with part of the spring moving inside) you should see it when you move the pedal by hand. i have a 99 z stock master though and it did squeak horrid. i used some synthtic brake grease on the pivot bushing (one that is on the master cylinder rod that slides onto the clutch pedal) and used some on the spring slot. also sprayed a little WD40 up towards the actually bushings the clutch pedal rotates on.
