they should work. if I'm not mistaken the Mirada has the 11.75 rotors (which is a good thing). You will need 73-76 A body upper control arms for the large ball joint to fit into the spindle. Also get the 73-76 lower ball joint which is a bolt in swap, nothing special. There's a couple of threads here detailing the swap step for step. Just type what you are looking for in the "search" box near the upper right corner and happy hunting!
