Overview

The alloy carrier is weaker (less able to handle the torque) but is lighter at only 9kg, thus keeping unsprung weight down — a perfect part for the lightweight Datsun Sunny 1000.

B10 4.111 (37:9) sedan & coupe
B10 4.375 (35:8) van
B20 4.625 (37:8) truck

All use the same #Gear Carrier
The bearing cap fit over studs and are secured with nuts, compared to the B110 cast iron H145 which uses bolts
Instead of the inexpensive crush sleeve that the cast iron H145 uses, the alloy unit uses reusable shims for side bearing preload

Distinguishing feature: studs fasten the bearing caps (cast iron carriers use bolts)

'37 X 9' stamping indicates 4.111 gear ratio (37/9), as used by B10 sedan and Coupe
