Can anyone offer up a part # or place to get this plug?
If the anode is completely
gone, there's no telling how long it's been
gone, unless you were the one who changed it last time. If it's been gone for a while, then you really need to flush the water heater, and see if the water comes out rusty. If it does, then you might be looking at a corroded heater core, and buying a new heater instead of an anode.
Parts66 carries anodes. So does Camping World. Price is under $20 per rod.
