Front Brake Caliper Identification help !

In looking in my " Hot Rodders do it yourself guide to:
Chrysler Performance Upgrades
The section on brakes says any single piston sliding caliper 76 thru 81 should work.
I think I will do what doc diff suggests and get remanned 78 cordoba calipers , the 11.75 rotors and the adapters and Im good !
Anybody done this ?
