New 1964 Dodge Dart GT Owner
The power box is longer, and requires a shorter steering column. The '64 column won't collapse, so you need one out of a power car. The coupler attaches differently in '64 than the later style, but I don't know if that is just the coupler that is different, or if the earlier boxes are different too. I haven't taken mine apart yet, so I can't tell you. I have the complete system, including the right column, but haven't installed it yet. It was for when my wife was driving the car, and she didn't like parking it with her 104 lb. frame, but she was still able to do it. I weigh 140 lbs. at 6', so I'm a scrawny dude, but can still drive my manual darts fine. I don't like the slow steering ratio, though. One thing to note--factory spec. alignment makes for incredibly easy steering effort. I was moving a customer's Roadrunner into the shop, which was manual steering, stock height, and stock alignment. It felt like power steering at a complete stop. My cars have positive caster, which doesn't make a difference unless the tires are rolling, but lower ride height, negative camber, and most importantly, non-stock tire size. These all contribute to a non-centered scrub radius. This puts the axis of steering rotation off center of the contact patch, so the tire is not just rotating, but being dragged forward and back a little when turning.
