9 inch hubs?

I'm probably not going to like the answer but here goes. 69 dart with drums, I need to replace the front drums and they have welded themselves to the hubs, no amount of persuasion seems to help at all. My last hop for them is taking to my mechanic and put them in a press but I don't have high hopes they will be usable afterward. Where can I buy them? Hubs or whole assembly.
