Davy,
I darkened your photo a bit to see the grill better, and also stretched the black point to see some outline of the body:
Here's a 1998 Ford Ranger, regular cab (I think it's definitely a regular cab of something, but the '98+ Ranger looks really close):
Here's a 1993-1997 Ford Ranger body. Looks pretty good too, but I'm leaning toward the 1998+ body:
The older GMC light pickups have pretty big grills and I didn't find one that looked like this grill. The newer GMC's have the GMC logo toward the top half of the grill, and your picture looks more centered. Toyota Tacoma's ~a decade ago have grills and headlights very close to the top line of the front face, and your picture looks like it's all dropped down at least a little bit from the hood; same thing for Chevy Silverado's, and they are also thicker looking than your picture. A 2000'ish Mazda B Series pickup was close, but I think the Ranger is closer. ~1998 Isuzu Hombre is also close, but again, the Ranger seems closest.
