Where can I find mounting rail hardware for single CPU G4 Xserve?

Hope this is okay to ask here, as its hardware, but still OSX Server related? I am wanting to mount my G4 single CPU 1 GHz in a four post rack now where I have a new G5 (keep them all together). I however cannot find the rest of the hardware for it that I got when I bought it several years ago, all I have are the dog ears that I used to mount it in a telco rack. I've looked on eBay, and a few other places. Surely this is available somewhere? I hope? Thanks... :mrgreen:
