Thanks for that, good lead.
The issue I have is that the flywheel on this vehicle (don't know the terminology) where the clutch disk sits in a recess in the flywheel. There is an additional recess where the "hub" resides (ie. the part of the disk that holds the spring buffers).
So the size of the hub of the disk is limited by the clearance inside the flywheel and what I need measuring. The outside diameter should be 215mm which is spot on for my use.
