Kelsey Hayes front discs

I have a set of Kelsey Hayes brakes I'm thinking about selling I was originally going to machine mustang rotors for bbp but am going a different route, what are all the parts people are looking for when they want to do a swap? Spindles and calipers obviously and I think I can separate the hub from the rotor is this all one would want for a swap? Or do they need the upper control arms and lower? Also what is a set worth around? I imagine the calipers would require a rebuild
