H hood

Well me and my brother had to take the radiator of my H to put a new water pump on. I know there are ways to mount a water pump then taking the radiator off but it was far easier to do it this way. But The problem that I have is that when it went all back together the hood would not hook down right. The front left side keeps popping off the flange, And also there is about a quarter of inch of area where the hood should be snugged up on the front tin that covers the radiator. I was wondering if there are adjustments to fix this . I would have pictures but It is blowing about 40 and raining so It will have to wait.
