the factory tabs on 73-up a bodies is inside of the strut rods, whereas the 72-earlier are outside. if you want to run those lca's, you will need to run the k frame as well since the sway bar on 73-up goes thru and 72-earlier does not.
just use a power disc master from a 73-75 duster. i think its bore size is 15/16". good for manual disc brakes.
