If your decal backing paper looks like this below? then the location is already determined for you, the red arrows indicating where the white backing paper of the decal lines up with the airgrabber door opening on the hood to locate the decal properly, just double check that the actual 440-6 lettering of the decal will "fall" within the main stripe on the hood and not too close on the edge of the stripe, make adjustments as needed...IIRC I gave you the hood stripe location several months ago?...good luck with your project
