On your service parts code label inside the glovebox, you will find several sections. The top line details the VIN number, wheelbase and model designation.
The second long section details all the equipment installed on your vehicle. This will be 4 or 5 lines of parts codes, such as "G80" (which is the limited slip rear axle) etc.
The bottom line will be the paint technology, then longer numbers representing the exterior colour (or colours) then a vehicle order number. Paint codes can get a bit complicated because of all the combinations of colours, two-tone finishes, upper and lower colours etc.
If you read your parts label inside the glove box and then post the lines here, we may be able to help. Look for numbers such as:
44 (Medium red metallic)
50 (Olympic white)
39 (Indigo blue metallic)
67 (Light tarnished silver metallic)
A typical code might be something like "L67 U44" which is a medium red metallic truck with a lower stripe of light silver metallic.
