That is a cool car and it is a bit odd being a Fury III ordered with a 426 Street Wedge, but unfortunately it is a C body and that kills the value on those cars. If I were to price it I would have to say somewhere around $7,000. I have some friends that deal mostly with 63-65 B Bodies and I asked them and they also said somewhere around 7, depending on what the bottom of the car looks like. Hope this helps.
