Ford Mustang Restoration Parts Guide: 1964½–1973 Suppliers & Costs

Mustang Parts Are Cheap, Plentiful and Uneven

More than 2.9 million first-generation Mustangs were built, and the restoration supply chain reflects that scale: everything from a complete Dynacorn body shell to correct-stamp trunk mats is available new, usually from several competing manufacturers. That competition keeps prices low — a classic Mustang is genuinely the cheapest American classic to restore per hour of work — but it also means the marketplace is flooded with parts of wildly varying quality. This guide covers who to buy from for each stage of a 1964½–1973 restoration and what each stage realistically costs in 2026.

The Core Suppliers

Three suppliers cover the overwhelming majority of a classic Mustang build. CJ Pony Parts is the Mustang specialist with the deepest year-specific catalogue and the best fitment notes. National Parts Depot holds one of the largest Ford restoration inventories in the US with strong original-quality reproduction. Summit Racing and JEGS cover the performance, brake and suspension side. eBay Motors remains the source for Shelby, Boss and Cobra Jet-correct original hardware that no catalogue reproduces.

• CJ Pony Parts: year-specific Mustang catalogue, best fitment documentation
• National Parts Depot – Ford: 1965–1973 Mustang restoration depth, high-quality repro
• Summit Racing – Ford Performance: engine, brakes, suspension, cooling
• JEGS – Ford Parts: drivetrain and chassis components
• eBay Motors – Ford Muscle Parts: NOS, Shelby, Boss and Cobra Jet original hardware

Where Classic Mustangs Rust — and What the Steel Costs

The rust pattern is completely predictable: torque boxes, floor pans, cowl (the notorious cowl-vent leak that soaks the floors from inside), rear frame rails, shock towers, lower fenders and quarter panels. Shock tower and torque box repair is structural and should not be economised on, because a Mustang with tired torque boxes flexes visibly and the doors will never gap correctly. Fastbacks command the highest values and also suffer the worst rear-structure rot.

• Full floor pan (both sides): $280–$520
• Torque boxes (pair): $180–$340
• Cowl repair panel and hat section: $220–$420
• Shock tower (each): $150–$280
• Quarter panel (each): $320–$520
• Rear frame rails (pair): $300–$460
• Dynacorn complete body shell (coupe/fastback/convertible): $16,000–$26,000

Interior and Trim: The Cheapest Big Win

Nothing improves a classic Mustang's perceived value per pound spent like a complete interior. Full kits from TMI, Scott Drake and Distinctive Industries — sold through CJ Pony Parts and NPD — cover seat upholstery, door panels, carpet, headliner and package tray in a matched dye lot for less than most single body panels plus labour. Do it in one order from one manufacturer; mixing brands produces visibly mismatched black-on-black.

• Complete standard interior kit: $1,200–$2,200
• Deluxe/Pony interior kit: $1,900–$3,200
• Moulded carpet set: $150–$280
• Headliner: $150–$300
• Instrument bezel and gauge restoration: $250–$600

Shelby, Boss and Cobra Jet: What Must Be Original

On a base coupe, reproduction everything is entirely correct behaviour. On a Shelby GT350/GT500, Boss 302, Boss 429 or 428 Cobra Jet car, the market pays for originality in a narrow set of components and punishes reproduction hardware harshly. Verify the VIN and the Marti Report before spending anything: a Marti Report (the licensed Ford production database) tells you exactly how the car left the factory, and no serious Mustang transaction above $60,000 should happen without one.

• Marti Report (Deluxe or Elite): $50–$250 — buy it before anything else
• Correct date-coded carburettor and intake for CJ/Boss engines: $1,200–$4,000
• Original Shelby fibreglass components: $2,000–$8,000 depending on part
• Correct rear axle and date-coded housing: $1,500–$3,500
• Reproduction is safe on: floors, glass, weatherstrip, interior soft trim, suspension

Realistic 2026 Restoration Parts Budget

A solid-shell 1966 coupe brought back to a strong driver typically runs $12,000–$20,000 in parts. A rust-affected 1969 fastback restored to show-driver standard runs $28,000–$45,000 in parts before paint and bodywork labour, which adds a further $18,000–$40,000 depending on shop rate and shell condition. As with every classic, the cheapest route to a finished car is buying the straightest, driest shell you can afford rather than saving money on the purchase and spending it on steel.
