They came from square headlight auto A15 sunny wagons, unless I'm mistaken.

I'd never heard of an H150 in 4.1 ratio.

According to datsun1200.com, they were available "in the Japan market 1976-1977 B210 Twin Carb A14T 5-speed model".

Are there any automatic square headlight B310 wagons in NZ? Only ones I've seen here are 4spd A12, with the 3.9(ish) diff.

Sorry, I was mistaken. The A15 facelift 310 wagon autos were fitted with 3.7 diffs. (at least in Oz)

H150 4:1 diff comes out in The B310 Sunny Automatic.
Had one which I just sold.
Have paid for one from a guy in Dannevirke just need to go pull it out of car.

Sunny service manuals state 3.889 for automatic, and 3.7 for manual, for all engines.

my old sunny sedan with a15 automatic had a 3.889 from factory.

if apparently sunny a12 automatics have a 4.1, they wont be common.
