'69 Z/28 value?

[southernfriedcj]

I've got a guy with a '69 Z/28, he wants to sell the car, but he won't name a price. He wants me to name my price, and he will take it or leave it.
The car is a 26,000 mile car that has been taken apart(and stripped of paint)since 1977. It is all there except one head is missing. It's been stored inside and there is no rust. The car is Green on green. It's not a 4 wheel disc or crossram car.
Does anybody have a ballparl value based on the description. I'm thinking 8-10k.

Thanks,
Jim
