Front Disc Help!

[jmartin99]

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!

I would start with Raybestos or Wagner then lookat rebuilders like Fenco or Cardone
 the calipers I order rebuilt come with them included

There's a superseded caliper bolt kit that is shorter than the OEM one's that were original. It eliminates the need for the caliper anti rattle vibration hardware.

I don't have the p/n right now but I will try and find it and reply back to you. I actually have a set and the instructions clearly say these are replacements for the older version. I won't be able to get to them till at least Friday.

I don't believe my 73 came with them. I've had the car since 22K miles & have done all the brake work since then.

I don't have all the details but it looks like you are trying to install '74 brakes on a '72 Challenger using a '72 FSM.

If I'm not mistaken, there are some difference with the '73-'74 cars and the '70-'72 cars, having to do with pin vs. slide type calipers.  Maybe someone else will chime in on this.  Not sure if it make a diffeerence in the issue at hand.
