my thought is the value here lies in the 340/727 and 8.75 the rest is just a matter of what would you pay for a roller project that's deep water.
yes, it's 68 fastback. yes it's numbers. but no fender tag or build sheet diminishes the value greatly to me.
i don't think it's 20, but i also don't think it's 10... split the baby and say 12~15 for somebody that absolutely has to have a 68 S car.
