This is a NOS Ford valve cover grommet which is correct for all 1968 1969 1970 1971 1972 Mustang and other Ford cars equipped with the 302 or 351 W engines.   It has the correct Ford engineering number and Ford logo cast into it just as it should.   This pushes into the valve cover and then the PCV valve pushes into this grommet.   All original Ford correct,  no import repro crap here!
