squeaking/popping/springy sound from clutch pedal under depression/release

[TurDz]

I did thorough searches on and off for a few months now, and I think I've narrowed down what causes my clutch to make noises after continuous use on the road (say...stepping on the clutch 40 times total within an hour).

There are two plastic sleeves (a hollow cylinder type shape, very tiny) that holds the clutch spring in place..one is pretty much eaten up and I'm pretty sure that's what causes the noise.

Has anyone tried replacing this piece yet? just by examining the clutch pedal assembly, it looks extremely tedious (as mentioned in an old thread on zilvia).
