I've read that the GT86 has a turn signal in the headlamp like the BRZ, and it's really not a close enough pic to tell but this looks like a molded ABS part covering up where the turn signal would go. I know the outer trim piece is the same part # for GT86 and FRS, I'm wondering if I can get that black plastic part that covers up the turn signal.
I'm actually rebuilding a wrecked car so I need to buy all new front end stuff anyway, so I have to buy fenders, garnishes, lights, bumper cover, fog lamps, etc etc etc and attach them to a tube front. If I can find the part # for two $5 plastic parts and order them along with the jdm fog bezels to save myself from ordering $130 turn signals since I'll be wiring the headlights as turn signals anyway, I'm that much closer to being able to order other parts I'll need.
edit: and the brake ducts are cool but I'd rather have fogs
