What is the overall width of an H190 Datsun Nissan rear axle and from what vehicle does it come from?

Depends which country you are in as to what the vehicle is called.

Datsun Stanza, Violet, 510, Auster, 160J and so on.

I'll measure one tonight and let you know in 18 hours from now (05:36 GMT = 16:36 AEDT (GMT + 11). I've got half a dozen at home

Often identified as PA10 by model designation

Forgot to measure - will do so tonight GD

Sorry, the H190 diffs are on cars at present. I have a couple of the Australian alternatives that I could measure.

They are both off Stanzas, with the Borg-Warner differential mounted from the rear of the axle, through it, and the flange to flange distance is 1280 mm. This is from the outside of the axle bousing where it bolts flush onto the brake backing plate.

The H190 diffs are in my Stanza and 720 rear ends. The Stanza banjo housing MAY be the same width as the Borg-Warner one. The track of the tyres on the ground is unchanged.

That's right, the 720 ute/SUV has the same differential H190 (something, depending on vehicle equipment levels) H190A, H190AL, H190*2 etc, in ratiOS from 5.1 down to about 3.8

DOES THAT PROVIDE YOU WITH ENOUGH INFORMATION ?
