Disc brake hub assemblies

[J3rm0ff]

I am looking to put together my own big brake kit. I have a 72 c10 with disc brakes now. I was going to buy cpp modular drop spindles. However I believe I need some type of hub bearing assembly that isn't a rotor. I see big brake kits Come with them but I can't seem to find them by themselves. The only other thing I can think of is to buy a spindle for drum brake front and buy a drum brake hub.
