i just googled scion xd billet grille. then found a site that had all the pieces i wanted. i got the top, bottom, and side billet grilles for around $100-$150. not bad and installed pretty easily.

this is the link from amazon that is a 4 piece kit. beware. it is only 2 pieces for the bottom grille and the 2 side slots

this is a link to the upper grille. so, this would actually be 5 pieces to give you the same grille i have.
