it also seems your a little new to Z cars, no prob , the pic you have is of a s30 not a 280zx(not a single body part off of a 240,260,or 280z will fit on a 280zx) msa is probly going to be your main source for body parts
there are several G-nose kits for the 280zx but your looking at a total cost of about 2-3k mabe more depending on which one you get
and flares for the 280zx are usually one off and sourced from other cars or custom made with fiberglass
