SBP Drums to SBP Discs Conversion

I acquired a set that haven't been used in 8 years. They have been sitting on a shelf, outside, at my friend's father's house. I now have them in my trunk. They are still assembled, and have the upper control arms, though I do believe I will not need to use them. I would take a picture, but it is raining and much too dark. I'll upload one in the morning.

I went to my local parts supplier (California Auto Supply in Pomona, California) yesterday and placed an order for all that I listed in the first post of this thread. I haven't picked up the parts yet, but will tomo. I will ask about the rotors, and whether they are the complete assembly. I doubt it, though. Should I order hubs too? I was told to buy bearings and races- are those the same thing?

I'm sorry if I sound stupid but I haven't gotten a chance to reference my service manual..

Anyways, the calipers I ordered are made by A1 Cardone.
The lower ball joints are MOOG.
