Can someone ID this grille?

It is on a 88 GMC dually. I want to upgrade the headlights and marker lights. I thought GMC's (maybe Chevies) had the 1 piece side marker. I may want to change the grille back to GMC, but want to keep a 2 piece marker light. Would like a solid black grille too. I guess I need to know the year of this one so everything fits the same.
Thanks.

Looks like the stock 88 grill, just painted.

Did the Chevy grille always have the 2 piece marker lights?
What year did GMC goto the 2 piece marker? Can I run a 2 piece GMC grille on my 88 without changing too much up front?

The one in the pic is a '88-93 chevy (silverado)
Chevy always had 2 piece side markers. '88-'93 markers were different than '94-99. GMC went to two piece
markers in '94 . When ordering 2 piece aftermarket side markers for GMC, make sure they are for a GMC, they are different for a chevy.
To convert to a'88-93 to a '94 up grille, you need the grille, filler strip, (body colored part between the bumper and grille) '94-up bumper brackets, and turn signal housings. (and side markers, obviously)
