The alloy body work does not define a Cobra. The chassis and its assigned VIN determine the validity of the car. Just as on any standard vehicle, if you wipe out some sheet metal and have to replace it, nothing changes regarding the car's identity. (Just ask CarFax...) Same with a Cobra. When CSX 2532 was properly restored, the incorrect fiberglass body was replaced with an alloy one. The car remains CSX 2532. As regards your definition of the term "Fobra," i consider it more reference to a kit-car masquerading as a real AC/ Shelby product, i.e. "Fauxbra."
