Any vendors have this part in stock?

[nightmare]

So I ordered the vacuum actuator (under hood) for my a/c system from LMC a couple of weeks ago. Not knowing it's a plastic piece of you-know-what, it, of course, broke as I was installing it. Since they have a no return policy, I decided to order the metal one from GMC Pauls. They didn't have it in stock, nor did any of his suppliers. I need to have one pretty soon, and DO NOT want the plastic one. Do any of the vendors have them in stock at the moment? Can anyone give me the AC Delco or GM part number for it? Thanks

I hope it's ok, I borrowed this pic from someone on here to show the part that I'm looking for. Thanks
