if the pedal gets spongy some of the time it sounds more like a clutch cable problem(not seating on the gear box properly). And if it's slipping out of gear, it's time to put a linkage kit through your car(unless it's a cable box)
Anyway check your gearbox code which you can find on the bell housing close to the engine sump from memory. That will let you find out what size spline you have on the box. Basically unless you are running a really early clutch the thingiwill be a 210 clutch with the smaller spline. The 16v boxes run a larger spline so you just have to make sure that it not one of those. (price is the same) I know someone in sydney but not down there. Golfwise is quite knowledgeable. He might be able to point you in the right direction in tassie.
