Kelsey Hayes disc brake setup 66 to 72

here are the pictures the rotors are Rusty I do not know how to separate the hubs from the rotors so you get everything the backing plates have a little surface rust will clean up with the light blast and the spindles are greasy they need to be cleaned this is a used set of 40 year old parts and I stated before the calipers I believe or Cores you may be able to rebuild them
