Pin Type caliper question

[superdart]

OK, so I have the pin-type calipers that I will be putting on my car. I have everything except the "positioners" in the attached diagram. I can't seem to find them in the parts store, although they carry everything else...

Do I really need them? Where do I find them?

I gave up trying to find those things. I run without them and the anti-rattle springs. Works fine, you just hear the caliper move around every now and then. Great for a track car, kinda unnerving until you get used to it on the street.

You can get them here.
Your question gets asked on a fairly regular basis, it seems.
