A body hood hinges

I have reached a point of serious frustration and am hoping someone here my know what I am apparently missing. I am working with my son to restore a 70 swinger and putting it back together am stuck with a hood hinge problem. I purchased a set of used hood hinges and after cleaning and painting, mounting them on the car, then mounting the hood. First time closing the hood one of the hinges, drivers side, bent, ruining it. I searched out a replacement, cleaned and painted it got it mounted and again the first time closing the hood it wants to bend also. I was watching so didn't bend like the first one, but still isn't working as it should. Anyone else out there run into such issues and any ideas how I can get past this point of serious frustration? I am nearly done with the body work and just need to mount the fender to finish them before I bring the car home for motor installation. Any assistance would be greatly appreciated!
