Schematic for front KH disc non-pwr needed

4"? Is this for your lawn mower? LOL Maybe you mean '4 piston'....
5 x 4" SBP K-H, the car was restified 23 years ago and the guys that did it took off the K-H front non-pwr disc brakes and put on 10" drums....i'm going back to original. My Chassis Service Manual from 1971 doesn't have any good pics
