Well I have obtained this os giken twin plate clutch I was told it was for an FD but im not positive. anyone here have any helpful knowledge they could share with me? I cant seem to find any part numbers on it.

 

I believe the OS Giken clutches themselves are the same for the FC Turbo and FD since they share the same splines and flywheel size.

The difference is that the FD requires an additional kit to convert it to accept a push type clutch.

 

hmm well I did a little research and it appears you are correct. anyone interested in an os giken clutch? needs a replacement housing as one of the bolt holes has sheered off, apparently there about 250 for a replacement piece.
