Rikuo 4 speed transmission

[gears]

Hello,
A gentleman recently sent me a transmission to inspect and rebuild.
It is a 4 speed from a 1950's Rikuo RTII 750.
I am looking for various bushings, needle bearings, and shifter forks.
Any suggestions on where to locate and buy would be great.

Thank you in advance
