It was the last year for push button, and the last year for ball and trunion driveshaft. In 65, they still used the two cable transmission, they made some changes. They went with a slip yoke drive shaft system, and on column shift cars, they went with an adapter for the cable on the steering column in the engine compartment. Console cars still used the same console, and shifter as used in 64. These trans are of interest to guys that want to eliminate the ball and trunion driveshaft, but keep the stock shifting mechanism.
