58 thunderbird

Hi I have a friend that has a 58 thunderbird that has been sitting for a long time. It has a good grille, front bumper, back bumper, tail lights, head lights, ect. I am wanting to find out what these are worth. If any of you out there know please give me a shout. If you know of someplace that i can go on the web to find out let me know. Thanks alot
