Where is the date Code stamped on a 67 Hood

[MyRed67]

  I have tried to locate the Date Code on my original (I believe) stock Flat Hood, with no luck.   I don't want to get too aggresive with cleaning until I'm sure where it's at.  Thanks for any help!!

  I have found the Hood Date Code stamp as well as many others.  The Hood stamp is at the very Rear corner of the Drivers side on my 11A - LOS built car.  I am attaching a pic..
