Designed and manufactured to bolt directly to a 9" Ford rear end, these brand-new brakes are based on the "Police Special" brakes of 1959. Measuring 11" in diameter, they are complete with backing plates, drums, 2 1/4" wide shoes, wheel cylinders and hardware. The drums come standard with 1/2" diameter mounting holes on a 5 on 4 1/2" bolt circle (other bolt circles are available by special order). The backing plates come with 1/2" mounting holes designed to fit "big bearing" axle flanges.
