***MODERATOR NOTE***
Moved to the correct forum. [MENTION=37095]Isaiahb97[/MENTION] the MT shifter assembly for the NSX is unique to the car and differs from LHD to RHD. I'm sure with a CNC and enough time/$$$, you could get a different shifter unit to fit, but who knows if the geometry will line up with the transmission shift forks?
What is wrong with your 92's shifter? Replacement parts are available to repair it.
