C7TZ-6A664-B Used before 02-21-1969. Original used hose that connects the original PCV valve to the carburetor spacer plate.
*Note - These molded and contoured hoses were designed to work with original style PCV valve (modern 90° PCV valves won't work). Additionally anything other than period original intake manifolds, valve covers, and spacer plates can also alter the position and distance in the relationship of the PCV valve and carburetor spacer plate.
