For the different engine, body and transmission combinations, Nissan used different ratios. For the MQ ‘era’ of vehicles (ie not MK), the standard ratio for any vehicle can be found in the Service Manuals, specifically MQ Service Manual (1980) Chapter 01 - General Information - GI-06 and Chapter 13 - Prop-Shaft & Diff - PD-34.
With the release of the MK, Nissan used different ratios, but did not update the relevant section(s) of the service manual. A table has been sourced from a Nissan dealer though, which does show the ratios. See: http://www.patrol4x4.com/forum/nissan-patrol-mq-mk-12/diff-gearbox-ratios-34049/
The following table is a combination of the service manual chapters above, and the table provided by Jelmer160. PS- T130A is the normal attached transfer, T100L is the rarer divorced transfer.
