Mine was rather beat up and out of shape as well. The screen was also gone and I wanted to put something in there. I wanted to firm up the rectangular opening and add a screen of some sort. I pulled out the shrowd and made a cardboard template of the top and sides of the front snout. I focused on the lip that falls just in front of the sway bar, about and 1 1/2" wide, as well as the sides of the snout. Cardboard allowed me to bend, shape, staple, and tape in pieces. I could then lay it flat to trace and cut a 1 piece reinforcement from some thin sheet stock. Layed flat it looked kind of like this

Double // and \\ to show some width.
Bend the sides down and it fits right over the leading edge of the shroud and hugs the sides. I drilled a couple of small holes in each side and secured it with some small machine screws. I used the holes that were already along the top lip from the factory screen, drilled holes in the reinforcement and secured with machine screws. I used these screws to secure a screen. I then shot the entire thing with several coats of black heat paint. I used a dull color to mimic the original finish of the plastic.
From the top you can not tell a thing has been done as everything if far forward. From the under the car you can see a little, mainly the ears that fold down on the side of the snout as well as the couple if screw heads. For the most part if someone bends over to inspect my shrowd under the car and has a comment, well they will get a foot in the a$$ hard enough to wedge their head under there.
From my point of view, yes it is not necessarily stock. I, however, can drive the thing and not worry about it. If I hit something or bump it putting it on the trailer there is little chance of messing it up. Should it bend, I can just bend it back "square".
Just a thought.
