#26 in this diagram. Part #26 is only the housing that is broken in your pictures, so you'd want #27-32 and #36 also all go with it if you were to buy a new housing and rebuild the assembly.
#24 and #25 in this diagram are the shaft and spring for the assembly in case there ended up being any damage to those.
I would just look around eBay or other sites for FZ6R or XJ6 clutch cable parts and assemblies. It might be a little difficult to find on its own because something like that is generally going to be left bolted up to any used engine assembly that's for sale. If you look at listings for engines that are for sale and they have it, you could always send the seller a message to see if they would be willing pull that pivot assembly off for you.
