1972 Chevelle 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.
You'll notice some plants used a three letter engine suffix code while some used a two letter code; Arlington even used both. All examples, so far, also used a three letter suffix code on the rear end axle ratio code.
You'll also notice that some plants code the rear end with the assembly plant first followed by the rear axle code and some will code the rear axle code first followed by the assembly plant.
VIN identification changed in 1972 in a number of ways.
>> The series was changed from a two-digit number to a single letter.
>> The engine size is now identified in the VIN.
