Tried this on a cossie and never found the space to hook the cable over the adjuster, the spring in there was too strong for me to hold it long enough, however if you lift the pedal and wedge something under it to hold it in place, that releases the ratchet, giving loads of slack to hook it over the clutch lever at the other end, then remove the brick, or whatever from under the pedal, and the cable goes tight as the ratchet does its job

The above works 100% on a cossie, not sure about an RST
