Sean, I almost did the same on my 91. However, when I took the grille and new fender and other stuff that I got after I hit a deer to the bodyshop, they painted the grille anyway. I didn't ask them to, they just did it. I'm glad they did now.
However, on your car, try it with just the black grille for a while, take pics and post them on here. We'll give you our thoughts on it. Then go from there.
