Just incase anyones stuck or fed up of theres failing first time its cold.
Get 2 hack saw blades, drill + angle grinding.
Keep the Rounded side to go into the frame, cut and drill to the other side to match the old Flex Link and put 4 pieces together, it's stronger and more flexible than the standard GT Link and shouldn't fail ever.
If 1 blade fails, 3 more to get you home.
Cheaper than a new 1 aswell.
