I can kinda understand a part that isnt boxed, like a bumper or fender being a cull that never made it to production, But anything in a box? No way. Production parts (say a carburator, or radio) wouldnt be shipped to production in individual consumer packaging….to expensive and too much waste and work for production personnel to deal with. I worked for Kenworth truck assembly plant for 17 years…EVERYTHING that was rejected by assembly was SCRAPPED, strict rule to ensure it never made it onto a truck.
