Calipers

The caliper is not carried in the Chrysler Parts catalog as an assembly. The piston housing is 3580 850-1. There are two different single piston, or sliding, calipers used by Chrysler back in the day, both were made by Kelsey-Hayes. The A-body used the one that uses the retainer clip to secure the pads.

Remanufactured calipers are available in the aftermarket. Rock Auto has Raybestos remans (FRC4067/FRC4067 ) for $81.04 including core charge. You may also be able to get them at a local big box parts store as 67Dart273 suggests. They have less expensive remans but the jury is out on the vendor's quality.
