I THINK your bumper won't accomodate the supports that go from bumper to grill guard. I believe it's the 06+ bumpers that don't have the bolt location for this. I know I've seen in mentioned here before, at least regarding light tabs and I'm pretty certain they go in the same place.
IF the above is incorrect, manik and westin make grill guards for our trucks, as does warn. The manik and westin look almost, if not, exactly identical. You'll be looking for the Westin 1-piece Sportsman grill guard. I don't know what the manik is called. The warn is called the transformer. Expect to pay around $350-$450 brand new for either I believe. I want to say my "approach angle reducer", aka grill guard, ran me $425. I got the westin 1-piece and ordered it though Checker here in town. I currently have it off my truck because even with the RCD lift it still kills my angle of approach, as well as hurting mileage. I was getting about 2 mpg average less with it on....prior to installing it I was getting 18-19.5 mpg, with it I saw as low as 15, but usually around 17 mpg.
