LT-135 came in two different connector types.

As far as I'm aware all LT-150 used same connector as Datsun 1200
Datsun 1200 LT-135 came with this type of connector

You will also have to get a slightly longer fan belt as the LT-150 is larger than the LT-135.

Possibly a different adjusting bracket will be needed too. I've never seen an A14 with an LT-135.

I used one for a 200b on my a15 before I sold the engine. Auto electrician had one on the shelf. Slightly bigger pulley and more amps I think. Around the $150 mark. It worked a treat. Just make sure the connecting plug is the same configuration as the alternator first

Get one from Supercheap?

Rebuilds are sold as Bosch AL237X (50A) or AL241X (60A).

Hitachi LT-150 came in these North America market cars:
* 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)

Have a 1200 ute with an a14 fitted and a filthy noisy lt-135 alternator

Only done minor research but apparently an lt150 will bolt straight up as well as other variants of this type of alternator. Anyone with a 50 amp or higher unit that will bolt up to the a14 or any details towards obtaining one feel free to pm or message 0468960681.

Cheers fellas.
