My '73 Dart had slider calipers on it, but they would rattle and clunk driving on cobble stone road, just like something heavy is about to fall off your car.
Had to rebend and even reinforce the tabs that maintain the calipers a few times, but they still got enough play over time to be audible. (We have a lot of cobble stone roads here).

When time came to replace the 10.9" setup, I just used what I had laying around;
- Late b-body brackets
- '73 Chrysler calipers
- '73 Rotors (11.75" & 1.25" thick)

Just needed 2 shims/washers to space the bracket out so the caliper aligned with the rotor nicely.
And an adapter collar on the spindle to be able to mount '73 outer bearing on the Dart's spindle.
