*NOTE: Some applications for this kit have the steering arm to the rear of the spindle and others to the front. Also, some applications have room to mount the bracket and caliper on the steering arm side of the spindle while the steering arm may interfere in other applications. The brackets in this kit may be mounted on either the front or rear side of the spindle. If mounting to the front of the spindle, the right hand bracket will be used on the left hand side of the vehicle and vice versa. This drawing shows a typical 1967-1969 Camaro left side application where the steering arm is to the rear and there is room to mount the caliper on the steering arm side as shown. Determine which way the bracket and caliper will fit best on your application.
