That's a very cool project. When you start it I'll be watching.
I've had a '65 SS stored in a barn since around '85. My parents gave it to me instead of trading it in 1978. They bought it used in 1967 with 10k miles on the odometer. They flipped it (the odometer) twice and added 50k more. My first date car.
After I finish my 68 Camaro, the '65 is my next project.
Good luck,
