fog light help

fog light help

Hey, I've got an '01 S. I noticed the other day that my drivers side fog light cover was cracked and filled with water. So I took a small air hose tube and siphoned out as much as I could and taped it off. Here's my question. Can I just replace the cover, or do I have to do the whole assembly? I called the local toyota, and they said the whole assembly... which they sell at 199.something (I found it online for around 130) plus an hour of labor at$75. This is just a fog light, which looks cool. I certainly don't need it, and don't need to waste 300 bucks to repair it. Is toyota lieing to me? Can I just replace the cover for like 20-30 bucks? The lights still work fine, although I've turned them off. Any help would be appreciated. Please email me at branchedout@aol.com Thanks

Mike.
