|The snap hook and pipe insulation (for padding)|
Loosen the frame bolts and slide a couple of lengths of pipe insulation down to the shoulder bar, with the snap hook in the middle. Cut enough insulation so both butt up against the tube bends, thus holding the snap hook in the middle of the shoulder bar.

Don't open the pre-cut slice in the insulation - that'll take some of its strength away.
