All 1974-80 Mavericks/Granadas with disc brakes as well as the Mercury versions are the same between the balljoints.
Be careful of the Lincoln Versailles spindles; apparently there is a difference.
You will need to run 1963-65 Falcon/Comet upper control arms (1965-66 Mustang are the same) as well due to their bigger balljoints.
Hint: when I did a 5 lug disc brake swap on a 1961 Falcon; aside from the
steering center link, every steering/suspension piece from a 1965-66 Mustang V8 will fit-------1965
only Falcon/Comet V8 are identical and, of course, the center link fits perfectly (2" shorter).
You will need 1975-80 Granada outer tie rod ends and I used the master cylinder/proportioning valve for a manual disc (read drum) brake from the same car. Brakes hoses from a 1974-80 Pinto finished off the front end
Rear end: 1971-77 Maverick 5 lugger with the donor car's backing plates work so your bolt pattern is the same front and back.
