The B110 uses a steering gearbox integral (one unit) with the steering column. Optionally available was a collapsible-column unit for safety in case of a crash. The collapsible column was standard for USA models. The gearbox is a relatively fast 15:1 ratio with only 3.3 turns lock to lock, and used a quality recirculating-ball type system. The only problem was a bit of play, as is common to boxes of this type, but as the years have gone by many boxes are worn out. Unfortunately no other gearbox fits and new ones are no longer available.
For modification-required swaps, see Steering Gearbox Swaps
The B210 and B310 units both have a seperate gearbox and column, joined by a flexible coupling. But these gearboxes will not bolt to the B110 subframe connection.

Interchange
Only Datsun 1200 gearbox interchanges. Made in Japan through 1994, and in South Africa through 2007.
B110 mounts with one front bolt. B210 and other mount with two front bolts. Cherry uses Rack & Pinion, so it does not interchange.
