I found two manufactures the produce the grills. They are fiberglass race bodies for baja and off road racing. The first has a full bolt on kits for F-150s and Rangers but do sell the grill seperate, especially if you are not putting it on newer F-150, like my 1996 F-250! The second doesn't have a good picture but it's coming. Found them watching the Off Road racing series on TV.

1: Ford Raptor Fiberglass for 2004 and newer F-150 the grill is not 100% identical but for $300.

2: PRODUCTS | BOATEC Fiberglass Race Bodies "racing body" $145

again these are aftermarket so they are not 100% factory look but for the price and fiberglass, they can be easily fitted to ANYTHING!
