Classic Car Carpet Colors: How to Find Your Interior Trim Code

Why Carpet Color Matching Matters

Ordering replacement carpet in the wrong color is one of the most common — and most avoidable — mistakes in classic car restoration. Unlike paint, which can be matched with a spectrophotometer, carpet color has to be ordered in advance. Get it wrong and you're either living with a mismatch or paying to ship it back and wait for a replacement.

The good news is that every American car built from the 1950s onward has a factory interior trim code that tells you exactly what color and material the car left the factory with. Finding that code takes about two minutes. Here's how to do it.

What Is an Interior Trim Code?

An interior trim code (sometimes called an interior color code or trim tag code) is a factory designation that identifies the specific color and material combination used in your car's interior. It covers the seat upholstery, door panels, headliner, and carpet — all coordinated from the factory.

Carpet manufacturers like ACC (Auto Custom Carpets) use these trim codes to produce replacement carpet in the correct color. When you order carpet from Jackson Automotive Products, you'll be asked to select a color — knowing your trim code ensures you select the right one.

Where to Find Your Interior Trim Code

General Motors Vehicles (Chevrolet, Buick, Oldsmobile, Pontiac, Cadillac)

On GM vehicles, the interior trim code is found on the Service Parts Identification (SPID) label or trim tag, depending on the era:

• 1950s–1960s GM cars: Look for a metal trim tag riveted to the firewall or the driver's door jamb. The tag contains a series of codes — the interior trim code is typically a two- or three-character alphanumeric code labeled "INT" or "TR."
• 1970s GM cars: The trim tag is usually on the driver's door jamb or the firewall. Look for a line that reads "INT" followed by a two- or three-digit code.
• 1980s–1990s GM cars: The SPID label is a white sticker typically found in the glove box or on the driver's door jamb. It contains a long list of option codes — look for the code beginning with "INT" or a standalone interior color code in the sequence.

Common GM interior trim code examples: 752 (Dark Blue), 13E (Black), 64U (Saddle). The exact color name varies by year and division.

Ford Vehicles (Ford, Mercury, Lincoln)

On Ford vehicles, the trim code is found on the Vehicle Certification Label (also called the door jamb sticker), located on the driver's door jamb or door edge:

• Look for the field labeled "TRIM" — it will contain a two- or three-character code.
• On 1960s Fords, the trim tag may be a separate metal plate on the door jamb or firewall.
• On 1970s–1980s Fords, the trim code is part of the certification label and is clearly labeled.

Chrysler Vehicles (Dodge, Plymouth, Chrysler)

On Chrysler products, the trim code is on the fender tag (a metal plate on the driver's side inner fender) on older vehicles, or on the door jamb sticker on later models:

• Look for the field labeled "TR" on the fender tag.
• On 1980s and newer Chrysler products, the trim code is on the door jamb sticker.

Jeep Vehicles

On Jeep CJs and early Wranglers, the trim information is typically on a sticker on the driver's door jamb or firewall. On XJ Cherokees and TJ Wranglers, look for the certification label on the driver's door jamb — the trim code is labeled "TRIM" or "INT."

What If the Trim Tag Is Missing or Unreadable?

Trim tags on older vehicles are sometimes missing, painted over, or corroded beyond reading. If that's the case, you have a few options:

• Check the VIN decoder — Some online VIN decoders for specific makes and models can decode the original interior color from the VIN. This works best for popular models like the Chevrolet Impala, Camaro, and Corvette, which have dedicated enthusiast databases.
• Consult a marque-specific registry — Many one-make clubs maintain databases of factory color combinations by year and model. These are especially useful for rare or high-value vehicles.
• Order a carpet sample first — If you're uncertain about the color, order a sample before committing to a full carpet set. We carry carpet samples through our Carpet Samples collection so you can verify the color match before placing your full order.
• Contact us — If you know your year, make, model, and trim level, we can often help narrow down the likely color options based on what was available from the factory that year.

Understanding Carpet Color Names vs. Trim Codes

One source of confusion is that carpet manufacturers use their own color names, which don't always match the factory color names exactly. For example, GM's "Midnight Blue" might be listed as "Dark Blue" or "Navy" in the ACC color selector. The trim code is the most reliable way to cross-reference — ACC's color charts are organized by trim code for most popular GM, Ford, and Chrysler applications.

When in doubt, use the trim code rather than the color name to select your carpet. If you're ordering from Jackson Automotive Products and aren't sure which color corresponds to your trim code, contact us before ordering — it's much easier to confirm the color upfront than to deal with a return.

Tips for a Perfect Color Match

• Order a sample first if you have any doubt about the color. Our carpet samples let you verify the match against your existing interior before committing to a full set.
• Match to your door panels and seats, not just the old carpet. Old carpet fades significantly over decades — the trim code gives you the factory color, which should match your door panels and seat upholstery if they haven't been replaced.
• Photograph your trim tag before any restoration work begins. It's easy to accidentally paint over or remove a trim tag during bodywork — having a photo ensures you always have the code on record.
• Note the pile style as well as the color. Your trim code identifies the color, but you'll also need to select the correct pile style (loop, cut pile, or mass-backed). Check your factory documentation or contact us to confirm which pile style is correct for your model and trim level.
