I am looking for a clutch to install now on my r32 rb26 but i also want to reuse the clutch for my OS Giken rb30 when it is ready for install. so my question is, I have heard of people using the OS Giken r3c clutch on standard 7 bolt crank. is their two diffrent versions of this clutch or will it work on bothe the standard 7 bolt and the Os Giken 8 bolt crank
