I am installing front disc brakes on a '72 Challenger for a friend. The whole front disc setup came from a '74 Challenger donor car. I bought reman calipers and they came with the hardware. Before I installed them I looking in the FSM to see how everything went together, especially the anti-rattle spring. I noticed in the FSM for a '72, there is piece called a "Positioner" that goes on the caliper bolts before they go through the caliper and pads. The hardware kit did not include them. Are they needed? Can you still get them?
Thanks!
