Mach 1 suspension VS Cobra suspension

I figure I will get flamed for asking this but is there an easy way to tell by looking if a car has a Mach 1's suspension or a Cobra's suspension? Apparently just looking to see which the car is isn't enough as I was informed today while getting some brake work done that my Mach 1 has Cobra suspension. I should have asked what year of a Cobra (I would assume '04 but I don't know for sure) but didn't think of it till it was too late. The car's previous owner only drove it for less than 2,000 miles but I do know that he put a different air system in it. If what they say is accurate I guess he changed the suspension was well.
 
If you are talking IRS (03/04 Cobra) as opposed to solid axle that difference is night and day. You would see that right off.
