Using mustang rotors for 4.5" bc

Oh ya, I like my 4-piston KH's instead of single piston later style brakes because the rotor rides at the back. The later style ones ride at the front. I would have to remove my front stock anti-sway bar to use later style large bolt brakes. Your Mustang rotor thing is the answer man!

Did you have to use the Mustang backing plate/shield thing?
