All 71-73 suspension was identical. There were differences that only Ford knew or cared about. I assume you are looking to install power disc brakes on your car? If you are, make sure you get EVERYTHINg that is associated. Spindles, hoses, steel brake lines, booster, proportioning valve, and the pedal. Allof these parts are different from a drum brake sytem, so get them while you are there.
An other goodies on that Mach? Maybe some of the VMFer's are in need of some parts......
