I will bet a crisp $10 bill that the hinges are straight and it's the body that is out of whack. But lets start with what EXACTLY is the problem? How is the lid fitting that suggests the hinges are bent?
Is it high in the back, low in the back, over to one side, high in the front up at the rear window, or is it too low there, what exactly is saying the hinges are bent?
I am 99% sure we can get this straightened out with the hinges.
