There is a problem with closing the hood with my '72 Challenger where the hood stays up on on the right side and needs to be pressed down to make it sit right. I know the hood should get adjusted to a certain extent but upon closer look there is a difference between the two hinges where they don't mirror each other.

The right hinge has a longer plate connecting the upper and lower arms that mesh together with teeth. The left plate measures about 3-1/8" long while the right one measures 4". Why the difference and is there an explanation.
