Hello and welcome the the forum! Try a search in this forum, using "hood lock" as the keywords. You should find plenty info on earlier posts regarding this subject. For my 66, I choose the conceiled pin lock type. The hand unit is mounted under the dash, and is connected to a cable, which you run to the front of the car, as you push the hand unit it pushes a pin through a bracket, which is mounted under the hood. Very simple and effective, and doesent show from the outside. Most all of the online mustang vendors have this kit for around $25.00. Good luck and again Welcome! James.
