KH disc brakes

Kelsey Hayes disc brakes off of a 71 dart. Stock equipment. Rotors, calipers, spacers, hubs, clips, hoses and spindles. I changed them for a set if wilwoods.
I did not like the hubs. They have been drilled for a big bolt pattern and the studs welded in. It's the three piece where the hub sits behind the rotor and the spacer in front. Also included is the correct (1966)? Mustang rotors, raybestos 6004R that eliminates the three piece set up. They have not been machined yet.
I'd like to get $350.00 plus freight for the lot.
Thanks
