Paint scheme for a 67-68 grill.

[prg machine]

I will be painting my grill soon and was wondering how the factory painted them when the grill was same color as body. The area in question are the 2 panels at the bottom of each oval opening that extend back in towards the radiator. They are about 2 inches wide. My grill was in white originaly and the area I am refering to was I assume a gloss black( flat now from age I assume) or was it flat black??

What have the rest of you done in this area. I thought at first about just painting them the same as body color as that is what I am doing to the grill. Would this look too bulky or wrong???
Any pictures/suggestions are most appreciated.
