Australian-assembled B110s and B210s used a Borg Warner rear axle assembly. These use a 'Salisbury' type differential, where the gears are embedded into the axle housing. Other B110s used the Hitachi Differential, with a removable "pumpkin" gear center-section.
- B110: Borg Warner Model 60
- B210: Borg Warner Model 68
Model 60
Australian-assembled B110s used a Borg Warner Model 60 rear axle, starting with chassis numbers:
- Manual serial number 54507
- Automatic serial number 40937
This started in Late 1971.
Apparently this is the same diff that was in AMI-built Corolla KE10, but those have a 4 x 110 wheel bolt pattern.

Model 68
Australian 120Y 4-dr Sedans from July 1976 were locally assembled and used a Borg Warner rear axle assembly. (BW model 68). All were 3.889 ratio. The 120Y Coupe, Wagon, and Panel Van, being fully imported into Australia, continued to use the Hitachi [Jap] rear-end in 3.9 ratio while the Van might have had a different [lower] ratio.
BW - removable back cover
Japan - welded back cover
The BW rear ends are pretty strong - meant to be stronger than H165.
This can be detected as there is a rear cover (the diff [center] doesn't unbolt from the front of the axle housing - like a GM differential only smaller). There will be a metal tag on one of the bolts that holds the cover on. It tells you which type of Borg Warner, and also the ratio (makes life easy at the wreckers).
They say Borg Warner on the bottom.
- it will be a BW if it has a removable cover at the back of the diff
- and either a H150 or H145 if it doesnt
The BW68 is the same width as a 1200 H145 diff, but have a different input flange, so you will also need the matching 120Y-BW tailshaft.
This is the same type of differential in the early Corollas.
