67-68 had a hand operated parking brake. 69-72 had a foot operated parking brake. A couple of minor changes were required in the cab.

The parking brake cable exits the cab in a different spot than on the 67-68, and the fuse block sits horizontal on the 69-72 instead of veritical like on the 67-68 to clear the parking brake foot pedal.

The 67's had different vent wing knobs, and the dash and maybe window crank knobs were different also, maybe they were carried over from the 1966 model year.

Also the outside door handles are unique to the 67 model year. Although the outside looks exactly the same, the mounting screw angle is different on the inside of the door. Outside door handles from a 67 will not fit the 68 and up doors, and vice-versa.
