1988 Dakota....flared rear fenders....?

Kinda looks like a Ford Ranger step side, the body lines on the flare/tub at the rocker very much are reminiscent of a late 80's-early 90's Ford.

I'm not saying it isn't an original or original dealer add on, I'm just saying I don't recall this ever on a Dakota nor does it appear to look like an assembly line piece.
