Chevrolet Build Sheet Lookup: Find Original Factory Specifications
There’s a unique sense of clarity that comes from seeing your Chevy’s complete factory build sheet—whether you’re verifying the original equipment on a classic truck or checking every option on a new Silverado.
You’ve just bought a used Suburban and want to confirm it has the trailering package, or maybe you’re restoring a ’67 Camaro and need to know exactly how it left the factory. The build sheet is the holy grail of vehicle documentation—it tells you everything from the engine and transmission to the paint color and optional equipment. Here’s how to track yours down.
What Exactly Is a Chevrolet Build Sheet?
Think of the build sheet as your Chevy’s birth certificate. It’s the comprehensive list of every component, option, and specification that went into your vehicle on the assembly line. Unlike the window sticker (which shows the MSRP and basic features), the build sheet includes every last detail—right down to the spring codes and axle ratios.
For enthusiasts tracking down a “numbers-matching” classic, the build sheet is your key evidence of originality.
Method 1: The RPO Sticker in Your Vehicle
The fastest way to find your Chevy’s factory equipment is the Service Parts Identification (SPID) sticker. This white or silver label is covered in three-character RPO codes .
Where to find it depends on your model year:
| Model Years | Primary Location |
|---|---|
| 1980s-2019 (most trucks & SUVs) | Inside the glove box lid |
| 1980s-2019 (cars) | Glove box, trunk lid, or spare tire well |
| 2020+ (all models) | Driver’s side door jamb (QR code) |
| C4 Corvette (1990s) | Under console lid or rear storage compartment |
The RPO sticker contains codes like G80 (locking differential), GU6 (3.42 axle ratio), and Z71 (off-road package). Once you find it, you can decode those RPO codes using free online tools or dealer resources .
Method 2: The VIN Decoder Route
If your vehicle’s RPO sticker is missing, faded, or you’re shopping for a used Chevy, your VIN (Vehicle Identification Number) is your next best option.
What the VIN reveals: The 17-character VIN contains the vehicle’s DNA. The 8th digit identifies the engine, the 4th-6th digits indicate the trim and series, and the 10th digit reveals the model year .

Method 3: The Dealership Route
For the most complete and accurate build information, your Chevrolet dealership is the gold standard. Here’s what to ask for:
- GM IVH (Integrated Vehicle History) report: Service or parts departments can pull this—it’s the complete factory build sheet .
- Original window sticker: Dealerships can often print a reproduction for newer vehicles .
The dealership route is especially helpful for vehicles that have missing or damaged RPO stickers. If your Chevy was originally sold in Canada, the dealer may need to check the GM Parts catalog for full RPO descriptions .
Method 4: Check the Hidden Build Sheet
Some classic Chevy owners have found the original assembly-line build sheet tucked away in unexpected spots. It was left behind by factory workers and can still be found :
- Under the seat (especially the rear seat)
- Inside the seat springs
- Behind the door panels
- Under the carpet
This is more common for older vehicles (1960s-1990s) but worth a look if you’re restoring a classic.
What Information Does the Build Sheet Provide?
Whether you use the RPO sticker, VIN decoder, or dealership, a full build sheet typically includes:
- Vehicle details: Year, make, model, trim level, assembly plant
- Engine and transmission: Displacement, RPO code, horsepower rating
- Drivetrain: Axle ratio, differential type (G80 locking vs. open), drivetrain configuration
- Exterior and interior colors: Paint codes (like WA8555) and upholstery codes
- Optional equipment: From towing packages to premium audio systems
- Original MSRP: Base price plus the cost of added options
