Curious that people install these box's without finding out any of the details of whats "in the tin" so to speak
This is a good UK resource for the "c" option box, in particular the FS5W71C
PhatTransmissions FS5W71C information - Main.HomePage
Spoke to the guy who used to do the work "Phat Bob" some time ago, he no longer rebuilds box's as its has become somewhat commoditised, but he pointed me in the right directions.
There is mention of the OS Giken gear kit on Phat Bobs page , I believe this was in 3 and 5 gear options, OS Giken page is here
OS Close Ratio Gear Kits | Products | OS GIKEN
Also these guys do them
Par-Engineering - Gearsets (Nissan)
NISMO | Silvia•180SX Reinforced Cross 6-Speed Transmission
And theres a bit of a clue here

Alternatively counting teeth is so much more fun
