It's hard to go wrong with a stock 69-70 grille assembly. New ones are quite pricey though. I would think you could look around and find a used one in fair shape and or smooth it up and paint or powder coat it in a nice shade of aluminum. I'm in a similar spot as my 69 grille was mashed on the outside edge around the headlight area. I have managed to put it mostly back in place but it's no where close to being ready to polish. I'm not big on painted grille surrounds but think it might look ok with the right shade of paint.
You're in a spot as that will always be her dad's truck.
