DL380 G3 Outer Rail Part Numbers

[orty]

(First off, sorry if this is already posted in the Business Support forums, but there appears to be more action over here -- why the duplicate places to post? Anyway...)

Looking to properly rack mount a couple DL380 G3s I've acquired. They have the snap on rails that attach to the server, but I need the rails that attached to my rack (a Compaq 9000 series). I've seen the part number for the full rail kit, I just didn't want to have to buy the whole kit if I didn't need to.

Thanks!
