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.

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.
