SGI320 voltage regulator

I ordered two new processors today but I need a second voltage regulator for the second processor. Does anyone know where I can get a VXI 073-20742-30 revK voltage regulator from VXI. This is the one that shipped with all 320s. SGI can order but it will take 5 weeks. Can you believe that sh@t? I tried going through VXI but I’m having trouble locating this company on-line. Perhaps there’s a compatible regulator from another manufacturer? Keep in mind I’m asking so many questions because this is all new to me. I’ve never upgraded a PC before; or an SGI for that matter. But, after this I think I’ll have everything under control. Soooo… anybody know anything about this?

Thank again everyone,
