Used 1970-72 black AUTOLITE marked oil fill cap with black plastic elbow. Several variations noted from our collection, AUTOLITE and MOTORCRAFT versions. Will need detailing or fresh black paint applied. Would also suggest replacing the rubber grommet. These 50 year old rubber grommets are rock hard and likely leak air. Gasket to valve cover will also need replacement. Even though this cap has a 1971 parts number, we see these on the 1970 351C engines quite often.
Replaces Ford part number D1AZ-6766-A.
