Well, kind of....it depends on the bodystyle.
There were no Mach 1 convertibles
Its also why you get the “5” suffix appearing on warranty tag color codes.
Yes, that much I know, I just didn't know they used Mach 1's for the Fastbacks, I'll correct that. Were they shipped for Shelby conversions less the Front End, Shaker, Deck Lid, End Caps and Side Scoops?
