I'm no expert but I do know that the Mach1s came with both a front chin spoiler and a deck wing. The regular sportsroof did not come with any but I imagine you could add some on as an option.
That being said, there's no reason you couldn't put Mach 1 spoilers on a non-Mach car. I did plus added the rear window louvers. You can order the spoilers from any Mustang parts supplier such as Mustangs Unlimited, CJs, Mustangs Plus, etc...
