Like said before, you should search the junkyards and a very good way to do this is through this website :
www.uneedapart.com
This is a site where you enter your info and it send e-mails to junkyards though out america with your info and they search their inventory for parts you need and if they have it they e-mail you back with info on it such as price warrenty and so on. It would be worth a try. But thats my 2 cents! Good luck!
