Unfortunately if it is the fly then replacement is the only option as it is not a servicable item.
Clutch replacement and release bearing is also advised when you have the gearbox out.
Exedy clutch kits, Fidanza single mass lightened aluminium flywheels and OEM LUK dual mass flywheels always in stock and good to go same next day.
Upgraded clicky axle kits also in stock
Let me know if I can help you further.
