I was in the same predicament (not enough time) and bought a repo chrome grille. I thought it would be a great shortcut and look sharp. I was wrong what a piece of chinese nightmare crap experience it has been. I knew better but still, I expected much more for my money than I got. I plan to roll with it until I can properly restore the original grill.
Just an FYI, it won't fit easily (the holes won't line up properly and you will ding your paint wedging it in place), it's flimsy, and I doubt it will stay shiny for long...
