out of commission, cant drive my dart anymore

Really?.. I really do want to get this back on the road..with disk brakes too being its a big block and still has the nasty 10" drums.. A long time ago i bought a very nice totally rebuilt kelsey hayes disk setup that came from a 1970 dart. New rotors and pads and all..ive just been scared to do the job along with a front end rebuild.. I dont remember a few things about this but something about using a different ball joint to use the disks and something about an adapter to do that so i dont have to change control arms or something..? I got to get this all straight in my head before i start..
