Just back to the caveat that in the UK, removal or decommissioning of an airbag which was on the car ex-factory will likely cause issues:
AI Overview
Having a steering wheel without an airbag is illegal for road use if your car was originally manufactured with a factory-equipped airbag.
Vehicle Inspections and MOT Rules
Factory compliance: Under standard roadworthiness testing (like the UK MOT test), any safety item fitted by the maker—including the driver airbag—must stay present and work properly.
Warning lights: An airbag warning light that stays on or fails its proper startup check sequence will cause an immediate test failure.
Removals: Swapping a standard airbag wheel for an aftermarket racing or deep-dish wheel without an airbag violates inspection rules for street-driven cars.
Insurance and Legal Penalties
Insurance invalidation: Removing safety gear and failing to notify your insurance provider can void your policy or lead to denied claims in an accident.
It's probably a year since a group of Morgan owners visited MotoLita and asked about their steering wheels with airbags; the response at the time was that they were working on the issue with MMC. Might be worth asking them first before making any decisions.
