When a COPO production order was released to Fisher Body it was for an L78 Camaro SS. A document titled "Exception Control Letter Sheet" outlined the components to be "added" and "deducted" during the production process for COPO 9560 & 9561. Among the items deucted was all SS badging. Since an SS-RS did not have the "rally-sport" fender badges the document deducted the "SS", leaving only the "Camaro" badge.
