When you get round to fitting it get someone to check that the mechanism isn't being fouled by the clutch lever arm when the pedal is fully depressed. That's an issue we've seen on Hawks that's resolved by filing off the right angle corner in the bottom right of the picture above, also check the bracket that clamps onto this rod for fouling in any gear, I suspect that's what's caused a sideways load on the rod and caused the fracture/breakage.
