The only catch is if you have this solenoid on top, I think it's called a speed sensitive steering solenoid or something like that. I believe it only came on the higher trim JDM / VX Limited. Makes it easy to turn the wheels at low speeds, and firms up at highway speeds.
Additionally, the solenoid housing where the steering shaft connects seems be a different length vs standard boxes. You can see mine compared to this pic from
@Box Rocket. But it does look like that entire back end unbolts... so I imagine to delete it the solenoid, you could just swap out that rear end and the steering shaft connection... not sure.
There are several threads on here discussing it, and talk of the lines being different:
Can anyone educate me on what this is on my JDM HDJ80 Steering Box? It’s definitely not on my FZJ80.

You'd have to go look at the steering box and see if you have that solenoid on top. I'm not sure what year they started using it.
Of course if anyone knows better than me, chime in, I haven't done too much research. I'm not ready to make the jump to a 105 box quite yet.
