Quote from: Cobramax on July 14, 2024, 02:11:27 PMThe engine number was stamped on the Shelby serial number tag on at least some 289 Cobras.Typically, the Cobra footbox tag began at the CSX22xx mark. (The beginning of the third contact of cars.) AC Cars Ltd stamped the VIN number on the tag and Shelby American stamped the engine number on the tag. Some Cobras below CSX22xx had footbox tags added at a later time. Perhaps some stated required an easily found and displayed VIN.
