As a final note, MANY of these cars interchanged alot of parts - almost everything was standardized from 73-up, so almost all the disc brake parts are interchangable, all based on rotor size 11" or 11.75"- for example, an '81 New Yorker 11.75" rotor can be used on a 73 Charger disc spindle with a caliper from a 73 Dart and a caliper adapter from a 77 Cordoba - the only consideration is that the caliper bracket must match the rotor size. You just need to think of the raw parts and not the whole car.
If you study through the tech pages, including the Moog Part # page, you'll find alot of similarities that will make your parts searches easier.
