I had this problem too, it eventually got so bad that the clutch pedal would not pop out that last half inch at the top.
I would buy the bushing and some beer to reward yourself after finishing this pain in the ars job.
It is a fifteen minute job that will take one hour of swearing before you figure it out. The part is like $7.42 and is part of the clutch pedal assembly. Be careful not to break anything else while you do it, because the job takes some brut force to get the spring back on.
Good luck!

You have two solutions:
1) buy a new plastic bushing from Nissan. It's most likely a special order part.
2) Remove plastic bushing and just lube up the join with some assembly grease (not WD40). The squeaks will be gone, but over a long period of time the contact and friction will eat away the metal on the pedal.
