hi guys

brother n laws got a late 80s nissan datsun double cab truck with a buggered diff,but we can find any plate or markings to say what the ratio is,are we just not seeing it or are they not normally labeled?,if we dont come up with any thing well just pull the face late off and count the teeth but were avoiding that at the mo,anyone able to help out?cheers in advance

The plate with the body number etc etc on it is what you are after. It will be under the bonner on the firewall.
The last 2 digits of the transaxle number is the ratio. Most likely 43, 46 or 48
