welcome to this site. when you replaced the fender did you remember the shimes? it looks like a U that sites around the bolt holes. this could explain the differnce . Also alot of repo hood will not fit right and will need some tweeking. fender and hood aligment is tricky and is like a lost art. But if it was hit in the front the metal is probbeen pushed up, so if you tap it down with a hammer, just a little at a time . fit and removel . it will take a while so be patiant. unless you want a body shop but it will cost around 80 bucks an hour for labor. im sure you can do it.
