Changing turnbuckle on rod rigging

[Icarus]

I'm looking at a C&C 41 with the view to purchasing it. One of the turnbuckles on shroud stays has broken and requires replacing. How is the turbuckle likley to secured to the rod Rigging?

I have plenty of experince of swaging wire on smaller boats and Hang Gliders but Rod rigging is new to me and any advise would be much appreciated.
