What a 1967 Mustang VIN actually contains

A 1967 Mustang VIN is 13 characters long, not the 17-character format that became standard in 1981. Each position in that 13-character string tells you something specific about the car: where it was built, what engine it had, what body style, and its production sequence. Unlike modern VINs, the 1967 format does not include a check digit or a model year identifier — you have to know the year separately, and you have to read the positions in order to extract the information.

Ford used the same basic VIN structure for all 1967 models, so the decoder logic works the same whether you are looking at a Mustang, a Fairlane, or a Galaxie. The difference is in what the codes mean for that specific model. For a Mustang, the body style code and engine code are what most buyers care about, because they determine whether you are looking at a fastback, a convertible, a coupe, and whether it came with a 200-cubic-inch inline six, a 289 cubic-inch V8, or a 427 big-block.

Key Takeaways

  • The first two characters identify the assembly plant: "7" for Louisville, "F" for Dearborn, "R" for San Jose, and "T" for Metuchen.
  • Positions 3 and 4 together form the body style code, which tells you whether the car is a coupe, fastback, convertible, or wagon.
  • Position 5 is the engine code: "T" for the 200-cubic-inch six, "C" or "K" for the 289 V8, and "R" for the 427 big-block (rare in 1967).
  • Positions 6 through 13 are the sequential production number, which shows the order in which the car rolled off the assembly line at that plant.
  • A 1967 Mustang VIN does not include the model year, so you must verify the year separately using the door tag or other documentation.

Breaking down positions 1 and 2: Assembly plant

The first two characters of a 1967 Mustang VIN identify which Ford assembly plant built the car. This matters because different plants had different quality control practices, and some plants built certain models more frequently than others. For Mustangs, the most common plants were Dearborn, Michigan and San Jose, California.

Read the first character as the plant code: "7" means Louisville, Kentucky; "F" means Dearborn, Michigan; "R" means San Jose, California; "T" means Metuchen, New Jersey. The second character is always a model-year indicator in later Ford VINs, but in 1967 it is part of the plant designation. Check your specific VIN against Ford documentation for your model year, because the exact meaning of the second character can vary by model line.

Positions 3 and 4: Body style and series

Positions 3 and 4 together identify the body style and the series (base, GT, or GTA). For a 1967 Mustang, common codes include "01" for a base coupe, "02" for a base fastback, "03" for a base convertible, "04" for a GT coupe, "05" for a GT fastback, and "06" for a GT convertible. Some sources also list "07" for a GT-A (automatic transmission) variant, though this designation was not always used consistently.

The exact codes can vary slightly depending on the source, so cross-reference your VIN against multiple Ford documentation sources or a Mustang-specific registry if you need absolute certainty. The body style is one of the most important pieces of information in the VIN because it directly affects the car's value and collectibility — a 1967 GT fastback is worth significantly more than a base coupe with the same engine.

Position 5: Engine code

Position 5 tells you which engine the car left the factory with. For 1967 Mustangs, "T" indicates the 200-cubic-inch inline six-cylinder, which produced 120 horsepower. "C" or "K" indicates the 289-cubic-inch V8, which came in two versions: the standard 200-horsepower version and the high-performance 271-horsepower version. The VIN does not always distinguish between the two 289 versions, so you may need to check the engine block itself or the door tag for that detail.

"R" in position 5 indicates a 427-cubic-inch big-block engine, which is extremely rare in 1967 Mustangs — most 427s were installed in Fairlanes and Galaxies that year. If you see an "R" code on a Mustang VIN, verify it against the door tag and the engine block, because it may indicate a non-original engine swap or a documentation error. Other codes may appear depending on the specific model and year; always cross-reference against a factory Ford VIN guide for 1967.

Positions 6 through 13: Production sequence number

The final eight characters are the sequential production number, which shows the order in which the car was built at that specific assembly plant. These numbers started at 100001 and continued through the production run. Two cars with the same plant code but different production numbers were built at the same plant but at different times — the higher number was built later.

Production numbers are useful for determining how rare a particular car is within its model year and plant. If you know the total number of Mustangs built at a particular plant in 1967, you can estimate how many cars were built before yours and how many after. This information is valuable for collectors trying to establish the originality and rarity of a specific vehicle. However, production numbers alone do not tell you anything about the car's condition, history, or whether it has been in an accident.

How to find and read the VIN on a 1967 Mustang

The VIN on a 1967 Mustang is stamped into the metal on the driver's side of the dashboard, visible through the windshield from outside the car. You can read it without opening the door by looking at the lower left corner of the windshield. The VIN is also printed on the door tag, which is usually located on the driver's side door jamb, though the door tag may have faded or been removed over the decades.

If the dashboard VIN is difficult to read due to wear or damage, the door tag is your backup source. The door tag contains additional information beyond the VIN, including the original paint color, interior color, and transmission type. If both the dashboard VIN and the door tag are missing or illegible, you can have the VIN decoded from the engine block or transmission, though this requires more specialized knowledge and may not give you the complete picture.

Common mistakes when decoding a 1967 Mustang VIN

The most frequent error is assuming that the VIN includes the model year. It does not. A 1967 Mustang VIN looks identical to a 1966 or 1968 Mustang VIN in structure, so you must verify the year using the door tag, the engine block casting date, or other documentation. Never rely on the VIN alone to confirm the model year.

Another common mistake is misreading the assembly plant code. The first character is straightforward to confuse with a letter when it is actually a number, or vice versa. "7" (seven) and "T" (tee) look similar when stamped into metal, as do "1" (one) and "I" (eye). Take a photograph of the VIN in good lighting and zoom in before you make any conclusions about which plant built the car.

A third error is assuming that the engine code in the VIN matches the engine currently in the car. Many 1967 Mustangs have been restored or modified over the decades, and the engine may have been swapped. Always verify the engine code by looking at the engine block casting numbers and date codes, not just the VIN.

Frequently Asked Questions

Can I tell if a 1967 Mustang is a real GT from the VIN alone?

The VIN tells you what body style and series the car left the factory as — positions 3 and 4 will show a GT code if it was a genuine GT. However, the VIN does not tell you whether the car has been modified, repainted, or had parts swapped. A real GT should also have matching engine codes, original trim, and documentation. Use the VIN as a starting point, then verify with the door tag and a detailed inspection.

What does it mean if the production number is very low or very high?

A low production number (close to 100001) means the car was built early in the model year at that plant. A high number means it was built later. Neither makes the car more or less valuable by itself — rarity depends on the specific combination of body style, engine, and color, not just the production sequence. However, early production cars sometimes have different specifications or known issues, so the production number can be a clue worth investigating.

How do I know if the VIN has been tampered with?

Look at the stamping closely. Factory VINs are stamped deeply and evenly into the metal. A re-stamped or altered VIN will show signs of grinding, welding, or uneven depth. If you suspect tampering, have a professional inspector examine the car. Altered VINs are a major red flag for theft or salvage history, and you should walk away from the purchase.

Is a 1967 Mustang with a 427 engine original?

Almost certainly not. The 427 was not a factory option for Mustangs in 1967 — it was reserved for Fairlanes and full-size Fords. If your VIN shows an "R" engine code, the engine has been swapped. This is not necessarily bad — many collectors intentionally upgrade their Mustangs — but it means the car is not original and should be priced accordingly.

Where can I find a complete 1967 Ford VIN decoder chart?

Ford's official factory service manuals for 1967 contain the complete VIN decoder. Mustang-specific clubs and registries like the Mustang Club of America also maintain detailed VIN guides. Online Mustang forums often have members who can help decode a specific VIN, but always verify critical information against multiple sources before making a purchase decision.
