I was able to find and purchase this same "Canadian" bug shield in Washington while browsing Burien Toyota's Parts store one day, which has all sorts of TRD parts and accessories in stock. The hood protector is made by FORM FIT, a company out of Canada, and looks identical to Loyd's picture above. Very easy to install (no need to drill holes in the hood; pressure holds this thing on very tightly). I paid $69.95 for it (plus tax).
