<-- back to Steering Column
A locking steering Column was a Datsun 1200 OPTION for early STD and DX models. It was standard equipment for USA 1200s, JDM GL and GX, and newer JDM 1200 pickups. The body of the steering lock is the same LHD vs RHD and early vs late. But the removable lock barrel, face plate and ignition switch differ. In particular, USA locks have a 2-wire connector for the key buzzer, while Japan locks say "Garage" on them. The Ignition Switch bolts to the rear of the lock.

Overview
Original steering locks were black, because the Steering Column Cover did not cover it. Aftermarket and perhaps later Datsun unit were bare metal
In all 1200s — both RHD and LHD — the Steering Lock bolts to the right side of the steering column.
The body is cast 'KV-1'

Security Bolts
A new lock comes with break-off bolts. Once tightened, the heads break off. To remove it requires tapping the bolts out slowly using a center punch, or using a hacksaw to cut grooves in the bolts.

Key Lock
The Steering Lock assembly has a removable key lock barrel. When purchasing a replacement, you might transfer the barrel to the new unit, or the new lock barrel can be re-keyed to match the door key. Or a complete lock set may be purchased instead.

Ignition Switch
The actual electrical Ignition Switch for this type is removable, and bolts to the back of the key cylinder. In other words, the Ignition Switch is not strictly part of the Lock Cylinder, but connects to it. A rectangular wire connector from the dash harness attaches to the ignition switch.
Fitment of ignition switch into ASSY-LOCK STEERING. There are three types: Large 2-tab, Large 1-tab, and Small 4-terminal
B210
B210 RHD used a similar steering lock as B110. But the USA LHD version was considerably different.
B210 USA
USA B210 steering lock is totally different. Clamps at mid-barrel instead of end. 48700-H6200 pictured with Ignition Switch attached.
B210 Japan
JDM B210 steering lock looks similar to B110 version.
48700-H5000 and 48700-H5010
(racer135- my RHD 1978 B120 uses a similar black 5-position key/steering lock barrel as the USA 1972-1973 mentioned earlier, albeit with a small single-lug switch with 5 terminals as pictured above. It may be exactly the same as the one above but there aren't enough photos to confirm. Also, when the start position spring failed in the switch, I replaced it with the switch from a Mazda 1000 ute I had for parts, which just happened to have the exact same switch!)
