As per the 'clutch pedal dropping' thread in tech, it seems I've broken the part that the clutch fork pivots on. In a fit of laziness, the box is still mostly in the car. I assume that there's a small part that screws into the gearbox that has the pivot ball on the end of it - that's the bit I need.
Anyone (preferably in Melbourne) have a rubbish gearbox or something they might have one of these things on?
