H190 Differential - 320 P/U
The Datsun 320 pick-up uses an H190 rear end that is slightly different than the later Datsun 510 wagon, Roadster and 520/521/620 pick-ups. The alloy case is lighter in construction with fewer ribs. I have been told (unverified) that the pinion gear shaft is smaller and uses smaller diameter bearings than the later H190 gear sets. This is a 4.875:1 ratio canter and weighs 31.5 lbs, as pictured.
