So now you have 3 grilles.
The white one, looks pristene in form... my guess this is going to be your target for mounting after modifications.
The chrome one you got with it totally looks salvageable; I would consider tinkering with it until it is straight, and reselling it. I do not imagine it would be hard to sell where you are, for enough to recoupe your expenditures at this point...
Your original that is currently on your truck is what I would use for experimentation. If you think this is going to be a time consuming effort, then I would rattle can the white one, and swap it out on the truck.
So there are some of the thoughts you asked for...hope it helps ya !!
I cannot wait to see how much better your grille comes out than mine, I hope you totally rock it
