I have brain strain but I've sorted it! My adaptor bellhousing to bolt the 4 speed to turbo patten block has the pivot ball 20mm to low (to the gearbox side) so the fork is 20mm to far away from the clutch. it has a threaded is pivot ball so I found a bolt with the right thread and cut the head off and welded a pivot ball to it and fitted with a lock nut on the thread at the right hight.
