Does anyone know if the 3-spoke steering wheel and airbag fitted to late Vectra B GSi will fit the Omega? They come up on fleabay now and again and I think it would be a nice addition to the MV6, as they're a bit more sporty than the 4-spoke ones. Since the Omega shares its 4-spoke wheel with the more sedate models of the Vectra B, I'm suspecting both the physical fitment and electrical connections are interchangeable, including the steering wheel controls.

Yes, it will. There was one on ebay not so long ago...
