I wouldn't want to pay any where near that $100. I have a guy that I'm talking to from Zilvia. He wanted to charge me $50+shipping until I told him that that was too hefty of a price. Once he realized exactly what I was talking about, he lowered the price to $25+shipping. Unless you want to beat that, I'm afraid that there is nothing else to do.

Edit:

The only piece I need is the reinforcement that runs from tail light to tail light. It's spot welded to the actual chassis. It's the piece that is all mangled up in the picture(s) above.
