Give my mate Kevin from GavSport.com.au a call (0296730988) and speak to him (tell him I sent ya), he won't spin you round the bush. Atleast that way you might have a bit more of an idea of what it'll cost you.
I had a spiggot bush ($10 part) go on me about 9-12mths ago and got a new clutch while I was at it, start saving for a lightened flywheel I say...
