On the Hornets and one gremlin I've done I've used the dics brake setup from the '83 Concord. I think thay work better than drums and the pre-80s disc plus theres room to upgrade pads because you can use the carbon-fiber pads from the Jeep Cherokee (#203 I think). And If you're running a high output motor you might want to upgrade 10 inch drums in the rear. And if you don't have power brakes you might want to add that also. Don't worry, it's easy to do.
