Posted this a few years back but maybe it will help here .
I start with the hood and radiator .

If the radiator is centered and the right height the hood to cowl gaps should be even all the way around .
If the gaps are tighter on the right the radiator needs to move left .
If the gaps are tighter on the left the radiator needs to move right .

MAKE SURE the radiator is level with the cowl !!!!!

If the gaps are wider at the bottom of the hood sides than on top your radiator is too high .
If the gaps are tighter at the bottom of the hood sides than on top your radiator is low .

There will be more but let us know what you have on this part .

Like already stated this is your foundation and all else works off this and a center hinge slightly long can really ball up the works .
