Caliper Rattle Options

[Stewbokka]

I have noisy rear calipers. They seem to be loose and the brake pads rattle on curtain bumps. I have replaced everything possible I think?
The things I've replaced - struts, springs, strut mounts, sway bar linkage, sway bar bushings, (all this was before figuring out that it was the calipers rattling)
And then the brake pads, calipers bolts, caliper sliders, and after all that I changed the calipers themselves and still the rattle. I was just hoping
maybe someone would know what it could be other than what I listed if so it would be much appreciated.

Thanks for all the replies...sorry for waiting so long to check for feedback on my question.
I have been to Toyota - so much that they know me by name...and they don't know of anything else that can be changed that I haven't already changed. I have changed the clips and the brake pads and that has not solved this irritating rattle. It doesn't seem to be the brake pad rattling but the caliper themselves that are moving, in turn making the pads rattle against my rotors...will this "fit kit" help? Any ideas would be appreciated.
Thanks
