Known issues by generation
Collectors should be aware of specific issues prevalent in the Mustang Fastback and Mach 1 series from 1965 to 1973. First-generation models may face rust in the shock towers, torque boxes, and frame rails, particularly if left exposed in Maine's variable climate. Engine-specific components such as casting numbers and codes must match for K-code 289 Hi-Po, Boss 302, and Boss 429 variants to maintain value. Verifying the build record for the Boss 429, typically installed by Kar Kraft, is essential for authenticity. Additionally, engine and VIN documentation play a crucial role in determining a vehicle's pedigree.
