need help finding part numbers PLEASE

The truck is a 2005 4x4 F350 single rear wheel, with coil springs on the front.
If someone can, then I would REALLY love to have the part numbers for the hub assemblies and the studs. As of right now I DO NOT have a part number (that I feel confident with) for the hubs or the studs. I do not plan to remove the old studs, I don;t have the time (or patience) PLUS I'm a cheap SOB so I plan to buy after market hubs (I have heard that OEM hubs come with new studs).
I also have a question about the safety of bad hubs. They are not groaning at me yet, but the wheel does have "hub play". How bad and how fast can I run into safety issues.
Reason for asking is, I need to travel about 400 round trip mile this weekend...serious safety concern? or mild safety issue?
