Where can I find…?

My 2001 Taco is missing one of those two little sheet metal firing underneath the headlight, is that little almost rectangular part installed between the headlight, the front grill and the bumper.
I don’t know his definition and don’t know were to find it online, maybe somebody can help me in this awesome forum?

 

Called a headlight filler.

Dealer or junk yard. They also have reproduction, you can find them on ebay for $15ea or $30 for the pair but you would have to get them painted.

My first choice would be a junkyard & try to find one that's painted assuming you have a stock color truck.

 

Thanks that's exactly it!
