I had a new clutch in mine at 45k but it was due to the slave cylinder leaking. They are internal in the gearbox and are a combined slave cylinder and trust bearing assembly.
Not that expensive if I remember (£80 I think) but mine had leaked on to the clutch plate. total cost was £650.
I noticed the brake/clutch fuild going down first, so if yours is dry this may not be the problem, but if you need a new clutch? I would advise you have a new slave cylinder at the same time.
