Those steering boxes are very, very simple mechanisms.
Ford used the same basic idea from the late 8Ns all the way through the 1980s on some models. And the bottom of the box, including the ball nut, sector shafts, etc was the same, even on the models with power steering.
That's not to say an 8N box will fit a 600 or 3000 but the simplicity is the same.
If you just want to replace one sector seal that should not be hard. Remove the steering arm and pry out the old seal.
Those sector seals are small flimsy things and very easy to ruin when installing. I made a seal driver on my friend's lathe out of a piece of pipe to push them in.
Even a piece of plastic pipe would work fine as they don't take much to tap in. Cut the pipe so it's longer than your sector shaft so you can tap on the end.
Getting the steering arm off is easy enough. I use a two jaw puller and heat. Even a propane torch with Mapp gas will provide enough heat. With medium pressure on the puller, heat it to a couple hundred degrees and it will pop off.
I would say on a scale of 1 - 10 with 1 being changing the oil and 10 being a full transmission overhaul that job is about a 1.5
One cautionary note: Be careful around your fuel tank with the torch. Make sure you dont have a leaky carb, etc.
The volatility of gas is just another reason I am increasingly liking diesels.
Good luck. The job is very easy.
