Remove the hood.
Loosen every bolt forward of the cowl. Fenders, inner and outer; grille; latch plate; anything that connects to the radiator brace. Sloppy loose, really back them off.
Use the fender to firewall brace rods to crank the fenders into "roughly correct." You can tell where that is by setting the hood in the "closed" position. Leave the hinges hanging and latch the hood. Take it off and crank the brace rods. Replace the hood, check tolerance. Repeat ad nauseum.
When you like where the fenders are, remove hood, tighten some bolts. Replace hood, check tolerance. If it doesn't line up now, start over.
By the time you finally have the fenders and grille lined up you'll be too tired and p!ssed off to actually install the hood. Save that for another day, as that's a royal PIA as well.
