CAMPAIGN IDENTIFICATION LABEL
Each vehicle corrected in accordance with the instructions outlined in this Product Campaign Bulletin will require a "Campaign Identification Label." Each label provides a space to include the campaign number, the five (5) digit dealer code of the dealer performing the campaign service and the date the vehicle was campaigned. This information may be inserted with a typewriter or a ball point pen. Install the label only on a clean, dry surface of the radiator baffle where it is readily visible (additional campaign labels are available on stationary order as Form 7901-709).
