The Datsun 1200 used a leaf-spring live axle with an H145 differential. This is a Hitachi design with 145mm ring gear. It is a lightweight unit suitable to handle the torque from an A12 engine. Light weight is good. Heavy parts take more horsepower to accelerate.

Maintainence

The stock Datsun 1200 differential is a reliable, long lasting part behind an A12 or A13 engine.

As long as it doesn't run dry on gear lube it will usually last forever. So check it every few months for signs of leaking.
The only common maintainence is to pack the rear wheel bearings every two years or so. This will also keep the bearings quiet and reduce gear lube leakage into the brake area.

Differential Lubricant

Since the differential is a typical hypoid-gear unit, you can use any lubricant designed for such:

the traditional "90 weight" gear oil
the newer 75W140 multi-weight gear oil

For maximum fuel economy, use a modern multi-weight gear oil.

The original specifications (which are still OK to use) are:

Specification: API GL-4MIL-L-2105
- CHEVRON Multiservice Gear Lub. 75,80,90,140
- ESSO Gear Oil GP80,90,140
- MOBIL Mobilube EP or GX80-90, 90, 140
- SHELL Spirax 75EP,80EP, 90EP, 140EP
- SUNOCO Multipurpose GearLub. GL-480,90,140
- TEXACO Universal Gear Lub.EP80,90,140
