Decode your Protect-O-Plate Warranty card

I have more examples but only list a few examples on these pages. If you request help with yours, contact me and I'll be glad to answer any questions you have. Include a photo of the Protect-O-Plate as plants often deviate during the model year.

Only Atlanta and Kansas City abbreviated the engine suffix code and rear axle code to two letters omitting the initial "C" letter (e.g., TW for engine instead of CTW or CF for rear axle instead of CCF). Arlington, Baltimore, Flint, Van Nuys, and Oshawa used the full three letter code for these two items.

Muncie 4-speed manual transmission broadcast letters as well as A, B, or C designations were included on Arlington cards.

Note: GM offers 2 explanations on decoding the VIN. Using the common 13637 as an example:
1. When describing the VIN plate: 1 ~ Chevrolet Division, 36 ~ Malibu V8, 37 ~ 2-door sport coupe
...and...
2. When describing the POP: 13 ~ Chevelle, even number (2,4,6,8) is a V8 - odd number (1,3,5) is a L6, 37 ~ 2-door sport coupe. The engine designations of 2, 4, 6 or 8 for a V8 engine, and 1, 3, or 5 for a L6 engine was determined by the series.

A V8 Nomad would be 2, Greenbrier/Standard would be 4, Concours/Malibu would be 6, and Concours Estate/Monte Carlo would be 8.
A L6 Nomad would be 1, Greenbrier/Standard would be 3, and Concours/Malibu would be 5.
