dude that sucks... That part is so freakin expensive! My friend removed his since it was completly destroyed and is looking for a cheap solution. what part of it did you break? He was thinking of buying a broken one and fixing it himself (tho I told him it's not gonna look good at all but he doesn't care). Let me know if you're interested... might save you a little bit of money that way.
Anyways, there is a website that sells parts for cheaper
http://www.mitsubishiparts.net/
I looked it up and the molding is priced at $251... which is waaay better than the almost $500 (holy crap) that mitsubishi sells for.

I don't know how they are since I haven't used them. But one person has said mitsubishiparts.net are good stuff.
Hope this helps. Let me know if you're interested to sell your broken chrome piece.
