I have an 5 speed conversion kit, which is an replica of one done by an member on here, in fact from memory he made the clutch fork for me. It is currently attached to an gearbox which will show you how it all goes together, all the machining and welding was done by professionals so is of good workmanship.
I might be able to provide you with an flywheel which you need to get machined out to accept an sierra clutch friction plate but the rest will still be all viva.
I currently have no figure as such in my head but please get in touch and make me an offer
