The US never got the Jimny so theres probably no one here that can tell you.
If your meaning the older Jap import Jimny that looks like a 413 I'd say yeah it would fit but if you mean the newer shape I don't know if that would fit.
I'd be useing a Escudo power steer box as parts a more plentiful than Jimny but if you want to go with that ring shane at TePuke autoparts and he should be able to tell you if it will fit up.
On a side note I see Mainfrieght never pick our stuff up on Friday so I will take it down to the depot myself on Monday morning.
