Aftermarket Steering Wheel Adapter Hubs
Contents |
Overview
Only a few Datsun models used the small diameter steering column shaft, including the B10, B110 & B210. The B10 used blinker canceling pins that were relatively close together & this made it unique. The B110 & B210 share the same specs so the hub/boss is interchangeable between these two models.
Most other Datsun models, including the B310, used a larger diameter shaft & the boss for any of these will be too big in the hole to fit the 1200.

Wheel Bolt Patterns
Other than a boss that bolts to the 1200 column, consider which Steering Wheels it bolts to:
- 3 x 1.75" PCD: APC, Superior, Grant
- 6 x 2.75" PCD: Grant (close enough to use with many 6x70mm wheels)
- 6 x 70mm PCD: Momo, SPW, Netami, Sparco, Mugen, NRG, OMP
- 6 x 70mm rotated: Grip Royal
- 6 x 74mm PCD: Nardi, Personal
For Nardi and Personal (74mm PCD) wheels, a thin adapterᴳ can be used to bolt to a 70mm boss. It also rotates the wheel slightly so it will be positioned correctly.
Horn
Horn contact in the steering column rides on the bottom side of the hub
With two-wire Horn Button:
- earth wire
- Horn trigger wire
With single-wire Horn Button
- earthed via the screws/fasteners

Slim Boss Kits
Short boss kits are totally worth it to maximize steering wheel to body distance.
Randoli: i got a boss kit (HKB Sports made in Japan) through disco bob (look him up on this site)and it was about 12mm shorter than the previous one. i find now my knuckles sometimes flick the indicator stalk. i'm 6'2" and the reach is perfect in a standard seat. so how short is too short
Slightly bend the indicator stalk to the right position. Ring spanner slid down a 1/4 and bend.
Alternatively, consider using a wheel with 'spokes' that are relatively flat, so they don't space it back further.
