Duster hood alignment

I'm not an expert, but, when setting body panels, you are supposed to set the door panels to the quarter panels, since they are your constant. Then set the fenders to the doors, and set the hood to the cowl, and fenders. If you move the fenders in or out, it could change the relation to the doors. Then you have to reset the doors if you can. And then you will have odd gaps at the fender/ cowl. If all else is good, and you just need some small movement, although I don't like them, a shim, to me, is best.
