I have a 99 Si, and im having concerns about its front bumper being the right one. As well as the way it fits on, because there's a abnormal gap between the hood and grille/bumper. Sometimes I look at it and the bumper looks low, is it possible that the radiator support is damaged and makes the bumper lower which makes that gap. Cause I've been getting a lot of hood movement when I'm on the freeway, as well as a lot of squeaking, till I open up the cushings, but that gap is still there....

 

I have the same problem which I suspect is the cheap aftermarket hood the previous owner had put on.

I'm taking mine to a frame shop to have it checked out pretty soon, I guess that's the only way to be 100% sure though.
