This item is an exact reproduction of the 71-72 A-body disc brake bracket. All factory disc brake cars had this bracket to hold the prop. valve to the frame. Drum brake cars did not have this bracket only the front disc cars. If the car is being converted to disc brakes this item is a must to place the valve in the right location so the factory lines will bolt into the correct location. All the disc brake companies use the wrong bracket that mounts up by the master cylinder. All 68-72 A-body cars mount the valve at the frame. The valve will only mount correctly with the use of this bracket. This bracket may also be used if converting a 64-70 A-body to disc brakes using the GM 5 port valve. Although not correct, since 64-66 cars were not available with disc brakes and 67-70 used a two part
