Slight change to the tubes I used to sell, people had issues with fitting the handbrake cable back plate clamp, so these tubes fit on the other end of the conduit, and fit into where the cable/conduit goes into the chassis. (You are buying a pair of tubes )
Also these are Stainless Steel so will not rust away.
You may need to take a little material off the threaded section on the cable itself if it doesn’t fit through the tube extender (as pictured).
You will still need to cut the return spring down as before roughly the length of the tube.
