This may be a bit late but are the fenders original?
Is the valence original?
is the hood original?

Assuming yes it should go back together correctly
If no you should have mocked up the assembly to ensure fitment.

Loosening fender attach hardware should allow you to open the span between the fenders to allow the valence to fit, but will also open the gap on the hood. If this becomes an issue you may have to keep the upper bolt snug and rotate the lower fender outward to fit the valence.

Door/fender/hood fitment took about a week for me to be satisfied with gaps and panel alignment. It can be a frustrating task, every time you move one item it creates a change in another location.

Good luck.
