[WANTED] trunk part that keeps it from slamming on my head

Sorry I dont know the part or item name but I need what ever that part is that goes on the deck lid of a 1964 Barracuda that keeps the trunk from slamming shut on my head everytime I open it. It looks like some type of shock or something but I have nothing there and my head hurts.

Any insight anyone, both myself and my head would appreciate it!

Thanks!
