Many different Datsun alternators and alternators from other makes can easily be fitted to the Datsun 1200. If you are running high-power headlights, off-road lighting systems, or high-power stereo gear, using a high output alternator is called for. Or, if you need to replace the 1200 alternator and have free or inexpensive access to different alternators, you might consider a swap. Lastly you might have a bad Voltage regulator, and by swapping to an internally-regulated alternator reliability increases since these use a solid-state (no moving parts) regulator.

Overview
There are two major considerations in a swap:
- Physical swap. How does it bolt to the A12 engine?
- Electrical swap. How will the new alternator be connected to the wiring?
Physical Specifications
Alternator Comparison & swap info
Stock Hitachi LT-135 35A
- Weight: 8.4 pounds with pulley
- Front flange (bolt ears): 13mm thick
- Distance between engine-side mounting ears: 80mm
- Distance between Adjustment bolt and mount bolt: 156mm
- 10.5mm diameter mount holes
- Diameter of body: 114mm (4.5")
- Fan belt center: 29mm from front bolt face
- Pulley diameter: 69mm
- Adjustment bolt: Flange threaded for M8x1.25 bolt
Electrical Connector
Datsun 1200 uses the typical 1970s Hitachi T-shaped connector:
- Field
- Nuetral point
Other alternators use different connectors. Since the LT-135 uses spade connectors, wiring should be pretty simple.
Hitachi LT-150
Hitachi LT-150 looks like it will bolt right in place of stock LT-135 -- but the alternator rubs against the lower radiator hose. It could be made to work, but is not recommended.
- 9.6 pounds: Bosch AL237X 50A 1974-1978
Hitachi 50 Amp (Bosch AL237X)
- CHEVROLET LUV PICKUP (1981 - 1982)
- ISUZU PICKUP (1981 - 1986)
- ISUZU PICKUP NORMAL CAB 1987
- ISUZU TROOPER (1984 - 1985)
- DATSUN 200SX 1977
- DATSUN 610 (1974 - 1976)
- DATSUN 710 (1975 - 1977)
- DATSUN B210 (1975 - 1977)
- DATSUN F10 (1976 - 1978)
- Fits same as Bosch #AL241X 60AMP
Internal Regulator Alternator
Sunny Truck
Nissan 23100-B9810 (Mitsubishi A1T22971/Hitachi LR135), 35A internally regulated is a direct physical replacement for the original (small) B110 alternator. It even will use the same fan pulley belt. It is wired differently however (see Hitachi LR Alternator Wiring).
Nissan 23100-B8910
Mitsubishi Electric Corporation A1T22971
12V 35A 1X23
LS wiring (see Hitachi LR Alternator Wiring)
CAUTION: T-connector is LS wired, not FN wired

Hitachi LR
Newer Datsuns from about 1978 came with an alternator with internal-regulator, the LR150/LR160, including fitment on newer A-series engines.
