Adapter Hubs for aftermarket steering wheels. These hubs bolt to the Datsun 1200 steering column and allow for using many brands of steering wheels.
Contents |
Overview
Only a few Datsun models used the small diameter (14mm taper) steering column shaft, including the B10, B110 & B210. However although the B10 had the same shaft, it used blinker canceling pins that were closer together so 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.
Factory steering wheel bolts to this shaft. Or you can bolt a converter hub (boss) to it instead and have your pick of aftermarket wheels
The back of the stock steering wheel has a built-in hub (1200 GL wheel pictured)
Compatible
The following vehicles can interchange stock steering wheels as well as use the same boss kit:
- 1970-1973 B110 Datsun Sunny 1200
- 1973-1978 B210 Datsun Sunny B210/120Y
- 1977-1979 S10 Datsun 200SX/Nissan Silvia
- 1970-1977 C120 Vanette/Sunny Cab
- 1978-1982 N10 Datsun 310/Nissan Pulsar
These all use the same splines, the some turn signal pins and are also horn-switch compatible.
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: Grant 3-bolt also APC, Superior (1.515" between hole centers)
- 5 x 2.75" PCD: Grant 5-bolt
- 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 (M5 bolts): Nardi, Personal
- 6 x 74mm PCD (M6 bolts): RAID, Dino, Gussi Italia
- 9-bolt with various PCDs and clocking: LeCarra/Loka, Moto-Lita
Adapters are 10mm to 14mm thick and cost $20-$40 USD.
Grant to Momo steering wheel adapterᴳ
For Nardi and Personal (74mm PCD) wheels, a thin adapterᴳ can be used to bolt to a 70mm boss. It also rotates the wheel so it will be positioned correctly.

Multi-pattern Boss
Multi-pattern boss kits usually support two of the most common types: MOMO type and Nardi type.
MOMO: 6-bolts clocked at 12:00 on a 70mm PCD Nardi: 6-bolts clocked at 1:00 on a 74mm PCD
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
- Horn trigger wire
Three-bolt Steering Wheels
3-bolt patterns Grant: bolts at 12:00 on a 1.75" PCD Sparco: bolts at 6:00 on a 2" PCD (50.8mm) Motamec: bolts at 6:00 on a 50mm PCD
4590
Grant 4590 steering wheel installation kit (adapter hub a.k.a "boss kit") will work with APC, Superior, and Grant 3-bolt steering wheels. The kit contains a die-cast hub adapter, horn button (with spring), Grade 5 bolts, and wiring. Fits all Grant Classic Series, Challenger Series and Signature Series Steering Wheels. Use the cancel roll-pins from the original wheel.
The Grant short boss kit is $38 USD brand new and in-stock readily available from multiple speed shops.
Grant 4590ᴳ
NOTE: As of January 2012, there are a rash of reportsᴳ that the Grant 4590 model sold on eBay does not fit the 1200.
The legit Grant 4590 DOES fit. And presumably the version sold by major retailers does too. Beware of eBay listings that say it fits the Datsun 1200 *and* the Datsun 510.
Grant no. 4590 fits * 1976-1978 F10 * 1976-1978 S10 * 1979-1982 310 * 1974-1978 B210 * 1971-1973 B110 $39 Manufacturer's Suggested List Price (2021) $36 Summit Racing (2021) $37 Jegs (2021)
Post Cover (adapter/column cover) available in: * Matte Black * Chrome (optional)
No. 470-3592 does *not* fit the 1200, but fits: * 1970-83 240Z,260Z 280Z * 1978-85 Nissan pickup * 1980-83 Nissan SX200 * 1979-83 Datsun B310 * 1973-75 Datsun 610 * 1974-75 Datsun 710
You can also use an adapter ring with 3-bolt Grant bosses to use "universal" Momo/SAAS-style wheels (6 x 70mm PCD with M5 bolts). $30 - $40 USD. With this adapter, it might make the Grant boss kit as tall as some others.

HKB Sports ON-06 fits Datsun 1200 and has a dual-pattern for Momo & Nardi type handles
Also includes the 1200-compatible horn ring and horn wire. It takes the stock cancel pins, so the factory turn-signal works as intended.
This boss has the wheel threads built-in, so no need for an 10mm adapter ring.

Slim Boss Kits
Short boss kits are totally worth it to maximize steering wheel to body distance.
Say you are tall and you can't slide the seat back far enough (such as a 1200 ute or 4-dr sedan). You need to wheel close to the dash, and farther away from your body.
Alternatively, consider using a wheel with 'spokes' that are relatively flat, so they don't space the bolt surface back further. Then a regular size hub can be used while still keeping the wheel close to the dash. If you don't like the "flat spoke wheel" looks, then a SHORT boss will allow you to use deep-dish wheels.
A SHORT boss kit also leaves enough room for a quick-release mechanism. These bolt between the hub and the wheel and most space the wheel out 25mm farther.
Short boss kit mean the wheel hits the t/s indicator stalk?
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
Solution: Slightly bend the indicator stalk to the right position. Ring spanner slid down a 1/4 and bend.
