All of the cowl plenums for 67 and 68 models did not have a 302 decal on the lid. When the cars were delivered, the C/P was in the trunk and a standard open element chrome air cleaner was on the carb when it left the plant. In most cases, dealers would not install the air cleaner! Many dealerships stated that it would void the warrantee if installed. Our research has indicated that many who bought the cars new either had to do it themselves or have a speed shop install it.
