id imagine that you should use brand new genuine nissan items, in most cases arp alternatives can also be found. Pm nicely to see if he can maybe get you a part number
don't buy new bolts just use the same ones. Also i had a ORC single plate clutch on my old s14 i had shipped over. I thought it was a twin plate but when i took it off the noise i had been hearing was infact the thrust bearing rubbing through the cover. The cover is mullered but the flywheel is mint and plates and bolts are find. If u need any of the bolts or anything just gimme a shout ok
New box going in too. Need to find the thread about rebuilding the current one. Need the syncro on 2nd done (and perhaps the circlip issue as preventative for future use).
