If Toyota dont have a listing then you may not find anything new. They are a genuine Toyota part as part of their genuine bullbar they supply. We call the "eyebrows" or headlight infills. Who knows what others call them?
I wreckers wont sell them to you unless they had them spare off a wrecked bull bar, but maybe worth sending some emails out with the photo and ask. Be ringing the 4wd or toyo wreckers around the country.
