Re: Window sticker question
They're ECL codes, they note specific items for the factory to use in conjunction with a specific option. These codes could note a different speedometer gear to be used depending on the rear end. This is a good way to bust fake paperwork if you have an ECL code book. Often times the forgers don't use the proper ECL codes. They may use an ECL code for a small block on a big block car.
