They have a m56 thread that would possibly fit your requirement.
Good luck

Thanks Darren, Yes maybe the thread is M56, though as Joe says, early UO stuff may be imperial. I checked the Baader site and they do have M56 click lock, but it appears to be a female thread and I need a male thread. Would cost over 80 Euro + post so maybe I will just buy the whole diagonal.

Thanks to all who have posted.
