Hard drive holders?

[CoolHands]

Hi. I used the carrier / holders off my old hard drive on my new one. I still want to use the old hard drive so I need new holders. But I can't find them anywhere? They screw directly to the side of the HDD and are kind of sprung loaded at the ends. There are two - they are independent of each other (i.e. not some kind of wrap-around design). Any ideas where to find similar ones?

here's some pics so you know what I'm on about:

You would only have received them with the case. If not, contact the case manufacturer. They are not normally sold with the case.
