Self-adjuster repair kit question (where does this go?)

[PumiceMan]

Hello all,

Rebuilding my 69 Sierra rear drums, with new wheel cylinders, hardware, and new self-adjusters. There's a small stamped steel piece that came with the self-adjuster repair kit, looks like maybe an anti-rattle clip or some such, but I have no idea where it's supposed to go. The old parts that I removed didn't have this clip anywhere. This is also my first drum rebuild, so I'm a little lacking in the experience department.

It's circled in red in the picture (assuming I posted it correctly). Any thoughts?

Thanks for your time!
