Here is my 70 Z28 4 speed that I purchased from the original owner in 1981. Non RS, deluxe custom interior. Z21 and Z87, 3.73 posi.

I have had two 69 Z's first 70. I am the 4th documented owner first two from the same family. Original owner took delivery of the car in Germany as a soldier. After one year in Germany back home to California the car went. Stayed in Ca until 2019, then to NJ. PO to me had the car 6 years put 200 miles on it. CE block balance of drivetrain original along with the secondary parts.
