No what I mean is the model years of c900 that had an airbag, I heard somewhere that they have a different spline count and diameter to ones that don't have it. The hub is for a wheel that only has a hornWhile doable (and it has been done) it is problematic the replace the wheel since the horn rides the same clock spring wiring as the airbag, and passing that through to an aftermarket wheel is generally outside the scope of a hub adapter .
