I have a buddy with an early NSX and a clutch system(the hydrolic part) that need work.

Anyone have an address for me to send him?

Yikes! thats an expensive bugger (the older ones are!)
Thats a double clutch on the old ones, its tight and parts are pricey. Please do NOT do this job if you are not sure of what it entails. But, Given that warning I will send you to nsxprime.com and if you do a search you will find what you seek.
