hey does anyone know if you can use the old upper control arm for my 72 duster with disc brakes from a fury i think that you have to get big ball joints for it but i dont know so if some could clear that up that would be great thanks

 

so know one can tell me if that will work or not, ok can anyone give me some advise on disc brakes for my duster what other car i can get brakes from

 

you'll have to do more research but the 73 setup should work but you might have to change both control arms. also note that the wheel bolt patterns are different.
