Swapping out a steering box options

[spdway1]

I currently have a 7-tooth box in my late 28.

1) If rebuilt to keep originality, would it be an improvement with modern-day parts? I know the design was changed for a reason.
From what I am finding no more Model A vendors rebuild them.

2) If I decide to go with a 2 tooth, how involved is it...steering column replacement, horn rod replacement, more money, etc

(Eric, don't respond because remember it is not worth your time)

Thank you everyone else for your time and response.
