4 Piston Kelsey Hayes Brakes

Hello. I am selling a complete set of 4 Piston KH Brakes. They feature the SBP rotors. I have the Upper Control Arms. Rotors. Spindles. Calipers and proportioning valve. The ball joints will need to be replaced. I put them on my car to test the braking, which is much better than my single piston calipers, but I need a big bolt pattern. Asking $400 or best offer, since I don't know what these are worth. Part is located in San Diego, will ship anywhere.
