I have a 1966 fast back mustang Shelby 350 clone 4spd 302. interior is in good shape disk brakes on the front over all a ok 10 ft car. However the frame rail need work front just patch and rear normal rusted deal. the tile is clear and show 74k original mileage. I know very little about older mustangs so I was wondering what is a car like this worth or should I say how much should I sell it for. Any help is appreciated.
