Hi Peter I replaced my clutch in February this year and was recommended by Kaz to replace the following to ensure a factory silky smooth origanol pedal feel and I have to say it certainly felt fantastic once fitted.
Both driveshaft diff oil seals.
Clutch release bearing fork.
Release bearing guide turret.
Speacial grease which is not readily available to buy in the UK (if you would like the small amount to do the job, pm me and I can post some out to you foc)
The reason for the new clutch fork and guide turret is because the small scratches and abrasions over time can cause the clutch pedal to feel rough if not replaced.
