The Nissan price is in line but the dealer will always be expensive. Why can't they just replace the bolt and not the whole clutch? First time my clutch was removed on my z31 there were two bolts missing on the cover but it never hurt anything. Search in the member directory under cities near you and send out a few E-mails. Maybe you can find a member to help you DIY. The job is not that hard and you'll learn a ton in the process. Good luck.
