1970 Chevelle Protect-O-Plate Warranty Card (Atlanta, GA)

Decode your Protect-O-Plate Warranty card

I have more examples but only list a few examples on this page. 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 (at least through November of 1969) 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.

Interesting to note that these two Atlanta SS-optioned Chevelles have the same transmission date even though the sequence numbers are 1,693 units apart. Also note on line 2 the rear end date. Even though the first car was built first, the second car has an earlier date stamp, 0924 vs. 1015.

Note this is a replacement warranty card as the owner's information is stamped on the card itself and not on embossed tape. This is also why there is a 3-letter suffix code on the engine and the suffix letter C on the transmission.

Stamping on this card is not consistent with the options ordered. Build sheet shows power steering, air conditioning, and radio but no disc brakes. So the gap between power steering (G) and disc brakes (J) should be one space, not two, and there should be a space between what would be the radio and air conditioning such as:
1 3 1 and not the 1 31 shown and would decode to:
