Help Please Workshop/Repair Manual

Hi

I have had my Nissan Patrol for a year now and in that time have not yet managed to find a maintenence manual for her.
She is a Japanese import 4.2td engine, built November 1997 ( but new shape 1998 model in UK)

I am leaving for an overland trip through africa in her in three weeks time so am now getting desparate to find a manual.

Our website is www.patrolingafrica.com.

Thanks
Patrick
