Dom, that's the typical 64.5 hood with front corners turned out. The date code looks like a May (5) date.The areas that were identified with the squares show the dimples, which wouldn't be on the first version hood.The first version hood was phased out sometime in later April '64
Some background: 1st generation hood - day one production in March until late April 1964. Folded corners (like a '65 hood), no dimples stamped into leading edge (later examples had four dimples for strength stamped into the leading edge of the hood).2nd generation hood - late April 1964 until late August 1964 - unfolded corners, four dimples stamped into leading edge. This is what most enthusiasts identify as "the '64 1/2 hood."3rd generation hood - late August 1964 until July 1965 - folded corners, four dimples stamped into leading edge.An 09D car would definitely have the 1st generation hood, with no strength dimples stamped into the leading edge, and folded corners like a '65 hood.
