Going blue in the face searching for part names and numbers. There has to be a Service Manual for these gearboxes / transmissions by Nissan in Japan. Any clues where to find them?

the problem child is a 92 Diesel huffer 5 speed manual. NB it's a RHD.

fyi the Haynes manual shows nothing but stick shift and the Nissan Service manual for the diesel engine is just engine. Would love the Nissan Service Manuals to match this.

cheers
