cheers guuys taking the centre with airbag i can do and takes less then a minute, just two screws. However the centre of the other wheel will not fit. I want to use the airbag centre minus the airbag.
I did look on the net about how it work and didn't mention explosives. Its talks about two gases mixing. see below.
There are three parts to an air bag. First, there is the bag itself, which is made of thin, nylon fabric and folded into the steering wheel or the dash board. Then there is the sensor that tells the bag to inflate. It detects a collision force equal to running into a brick wall at 10 to 15 miles per hour (16 to 24 kph).
Finally, there is the inflation system. Air bags are actually inflated by the equivalent of a solid rocket booster. Sodium azide (NaN3) and potassium nitrate (KNO3) react very quickly to produce a large pulse of hot nitrogen gas. This gas inflates the bag, which literally bursts out of the steering wheel or dashboard as it expands. About a second later, the bag is already deflating (it has holes in it) in order to get out of your way.
the last part is the worrying part as is it only the sensor or as trashbat said the control unit that that tells it to inflate.
