For me...if its just the shell and nothing else, then $9,000 is too much.
If that includes the 440 and transmission, then good deal.
PS... If there is no interior at all you will spend at LEAST $5,000 for the seats, door panels, rear panels, dash board, and gauge clusters.. not to mention the wiring harnesses will be probably around another $2,000... Glass another 1500... another $4,000 on nice wheels and tires, etc etc...
Find a real nice ready to go car for in the $30's and save your money and headaches !!
