This is my other Chevy. Its a 1970CST Chevy with a factory 402BB, 400 turbo automatic, AC, Tilt, Posi (added), AM-FM (added), tinted windows, Buckets, Tach. Two Tone Green - factory colors. GM 8 Tract, GM Compass, GM Tissue Dispenser.
In 1970 GM had a truck strike and the production numbers were low this year. A guestimate is less than 5% of Chevy trucks were produced with these options.
