Sorry to tell you, shaker hood scoops are far from being Mach 1 unique. CDC was selling their kit for the SN95 Mustang GT, long, long before Ford even thought of doing the Mach 1 show car, let alone the production 2003 and 2004 models.
BTW, the Mach 1 prototype show car actually used the CDC shaker kit.
A better analogy would be putting "Cobra Jet" badges on a Mach 1, that doesn't actually have a Cobra Jet engine under the hood.
maybe it's cause I'm old enough to remember Shakers the first time around, but to me Shaker = Cobra Jet (or Boss)...whether it's a Mustang or Torino or even a Cougar
