yeah that does sound like the hood's been tweaked - what happens if you close the hood w/ no springs and latch out, and then push the back corner down? does the front come up? if so it's definitely tensioned wrong - if it still has the X brace rods under it, they're what is used to fix that, tho it ain't easy - if those rods have been taken out, that's the problem, or if the weld where they cross has been broken free
how about all the rubber bumpers along the front and at the back? if they're missing that could influence it too - can't think of anything else, and messin w/ the core support position will throw the fenders outta whack
