Used cast dual sheave alternator pulley. Casting number C9AF-10A352-C, we believe that these originally had a zinc dichromate finish. Called out for use on various 1969-70 Mercury Cougar and Ford Mustang with a need for a dual sheave alternator pulley. Just a tiny bit smaller than 2-3/4 inches in diameter.
*Note - this is a cast pulley instead of the common stamped steel single sheave version.
