front valances are for wimps :D
i did a similar thing over two years ago and i still havent put anything there. at work people constantly ask when i am going to put a bumper on it, at one point they wanted to get me in trouble for not having a bumper (the army micromanages everything) so i had to explain to them that the bumper is infact there and it is mearly the valance that is gone. ive looked at james duff but i dont think they make bumpers for the 01. it may have changed since the last time i looked.
id do what everyone else is saying, if you offroad alot, keep the valence off, or come up with a quick release system that removes the valence when you want to offroad, cause you will just rip it off again
