is it possible to add overfenders?

i think i made a small error in my 2018 sr5 purchase. i thought that black overfenders were standard, and color matched were extra, and i think i even asked the salesperson and they agreed. i pick it up tomorrow so i stopped today after work to check it out....and guess what? no overfenders at all. i get home and check the literature, and sure enough, no overfenders on the sr (which for some reason i thought black was standard and color was upgrade for sr5). anyway, can they be added? i'm guessing they must be clipped in at the top somehow, so drilling would be required.

thanks.
