[Closed] Wobbly Oval Concepts 730 crank arm - Non drive side.

I'm working on a bike for a friend and the non drive side crank arm is wobbling on the spindle when the retaining allen bold is fully tightened:

I think that there's a spacer missing from inside the non drive side crank arm. The Octalink spindle sticks out about 1mm and when the locking nut it tightened it rightly tightens up against the end of the spindle, leaving 1mm play for the spindle to rattle around in. If you get my meaning.

Surely there's an Octalink shaped spacer missing:
