We are happy to announce that the General Motors Protect-O-Plate Decoding Guide: 1965-1972 has a new stronger and more durable binding.

What is a Protect-O-Plate you might be asking?? Good question.

Back in 1965, General Motors came up with a strategy to track cars under warranty so they could better serve their customers.

Their idea/strategy was to mount a Protect-O-Plate on each vehicle. The Protect-O-Plate was like a metal credit card that encoded the major equipment and components on the vehicle. The Plate includes info from engine to carburetor, transmission to axle, from exterior colors to options.

This is kind of cool information for a restorer.

The General Motors Protect-O-Plate Decoder Guide: 1965-1972 Chevy Models, by PAH Publishing, covers:

  • Chevy Camaro
  • Chevy Chevelle
  • Chevy II
  • Chevy Nova
  • Corvette
  • Corvair
  • All full-size Chevy passenger cars

Today, the Protect-O-Plate, ranks as one of the best all-time documentation pieces for your car. The trouble is all this data is in code.

For example, what does code 1133333 mean? The answer can be found on page 18...

The codes are actually quite simple to understand once decoded. This manual/guide provides the detailed decoding information for all vehicles referenced so you will be able to decode any 1965-1972 GM Protect-O-Plate line, by line. That's valuable information...
