Need source for high current HP type (with dimple) 14 or 16AWG 110vac power cord

Need a power cable for the Netserver, they got one with all of the machines they bought for resale so I have to locate one. It's a standard PC type (HP) plug on the server side except that it's got a dimple on the side opposite the angled corners and it's either 16 or 14AWG due to the 12A draw of the server. I also assume it to have a different plug, not sure though. I'm sure that other applications use the same thing with all the heavy servers out there and that someone has an aftermarket source or has a few ratholed with no immenent use for it/them. HP has theirs listd for US as 8120-5395 but is no longer available (go figure - no power cord and you have a useless server). I really don't want to chance grooving a standard 18AWG cord and watching the fire dept as they hose my shop and new server down. I just checked JDR and Jameco - Jameco lists a standard cable at 14AWG but no real picture of the end, just a generic photo/figure. Now it's time to dig out the Mouser and Digikey catalogs - might find the HP end that I need, I have plenty of heavy duty power cables with regular female outlets (some 12AWG) that I can use. In that case I could even wire it direct or to 220 (autoranging/adjusting unit). Have to research a little I guess.
