Need some opinions, hood pins? Options

[KaJuN]

My hood tends to jump around alot while i'm driving, and it makes a LOT of noise while doing so. I've compared it to my wifes celica, and the hinges are identical, have the same amount of movement and everything, no latches are missing, everything is seemingly identical. So what i've resorted to is MAYBE using hood pins. I guess i would place them at the top of the hood (near the windshield). Anyone ever done something like this before? is this a bad idea? I'm thinking out loud, so don't be afraid to harshly criticize my idea if necessary. thanks!

it doesn't jump around in the front, just at the back by the windshield. if you grabbed the hood by the windshield while the car is stationary, you can move it up and down probably an inch, inch and a half.
