Needing 3/4 ton floating hub

[goregalore]

I am sorry for posting this here. I tried to post in the want ads but couldn't do it.

I have a 67 GMC 3/4 ton with a floating hub rearend.
I am trying to get my drums turned and no one can do it at a standard auto shop like napa etc. I had to take it to a heavy duty truck shop, and they want me to remove my hub to put the drums on and then they can line them up correctly on the lathe so they will be perfectly in the round. But the rear end in this truck has just been completely rebuilt and I don't want to take it apart just to get a drum turned.
So, I am looking for one floating hub. It doesn't matter if driver side or passenger side. I have looked at the local yards with no luck even with friends working there. Anyone want to part with one.
Again sorry for posting in this forum so please move if needed.
