when I came to fit this, the following 3 bits were in the box, presumably that's not meant to happen.
Am I right that the 'middle bit' goes on to the mech body where it bolts to the hanger (face to the camera goes into the mech)?
Then the spring washer goes in to the slot marked with the green arrows, to retain it? (Is this bit essential, it's a faff)?
Is anything missing?
