Grill mounting brackets ?

Please forgive me if I sound ignorant, but I am looking to replace my current 2016 Limited grill with an aftermarket grill. I have the grill for sale on FB and a guy just asked if the mounting brackets come with it? Would I need these brackets for the new grill or is it totally different for each grill? I haven’t poked around under the hood enough to answer this question so I’m turning to you all fine people...please advise

 

The grille is held on with plastic tabs and the hardware along the top. There aren’t really any brackets. You reuse the hardware on the top with most grilles and many aftermarket grilles use the current surround after you cut out the insert. Be careful not to break the tabs the first time you remove it, it is pretty simple once you see how it goes together.

The bulge is pretty similar

 

There are no mounting brackets per se. It's all integral.
