I just fixed this on mine and thought I post it for everyone.

most of us probably have an inch or two of freeplay in the clutch pedal before it actually engages. if the master cylinder is not leaking, and there is no air in the system, then the problem is generally from two other sources.

either the pin connecting the master to the pedal is worn and grooved
OR
the U at the end of the arm of the mastercylinder has wornout elongated holes.

in realitly it is going to be a little of both. this is usually due to the junction not being lubricated and its just metal on metal contact. this junction is also make a funky squeek sometimes if its not lubed.

to prevent and fix this, remove the pin and inspect it for worn grooves.
if its not wornout, just grease it a bit and replace it.
if its slightly worn, replacing it with a new pin will eliminate most of the play.
if the condition is bad, then the U on the mastercylinder is also worn out and almost always, the master itself is on its last leg by now so get a new mastercylinder which comes with the complete arm.
The U at the end of the rod is MB012124 but i don't know how much it costs.

here is something else thats interesting. the dealer is the cheapest source for the clutch master cylinder
well maybe not the local dealer but any of those online ones will have it for around $60 MB012099

Art,

Great post on a common problem.  I'd like to add the part number for the clutch clevis pin: MF473490. It should cost about $3.00.

Rgds,

I've also seen the hole in the pedal itself elongated/worn the same way.
