Because that kit is a reproduction of the '73-'76 A-body brakes, the calipers are designed to mount toward the front of the car.
If you install calipers facing the rear, the supplied OEM style hoses will not work. Although shorter (15") flex hoses will reach, I prefer to substitute '82 Diplomat calipers, as the hose routing is much cleaner for rear mount applications.
If you hear a "clunk" while braking, you must the bend the tangs on the brake pads, so they fit tight against the caliper. This is standard procedure for any Mopar sliding caliper. See below:
