Smallest Steering Box

62-72 uses a small sector shaft. Your 73 uses a large sector shaft. The sector shaft is where the pitman arm bolts up to it. I thought they made a 73-76 large sector shaft steering box.

That helps a ton! It looks like this is it. Do I need anything else, or will this just bolt right in? I don’t know if I’ll need to still shorten the steering column as I already have power steering.
