Those are the hinges and If it was me, I would probably take the the time to fix em up...the old stick holding the hood up is a great idea untill a gust pf wind slams the hood on your windshield ruining your bodywork and cracking your glass.....ask me how I know.....oops.
You can heat up the rivets and hammer them flat of install new ones to tighten them up. Another option once you install the hinges is to not open the hood so far that is locks at the full open position.....The hinge design is poor at best and worse when worn.
You can see in the pic my fatty and confused's notch...both hoods are open but neither is open fully.
Good looking lady by the way...I have a pretty brunette my self. :-D
