ohhh youllll be sweeeeeeeeet au, jeff showed me how to do it
i think for legal purposes you can get away with replacing it with an aftermarket wheel WITH an airbag in it. These i dont think they sell in NZ, but i remember someone telling me this.
As to getting the wheel off, mine didnt hav an airbag, just one bolt in the bottom, then the two top things were just plugs which you pulled like a mofo on the horn piece till it popped out.
then u need a socket set, unscrew middle, (NOT ALL THE WAY) leave some of the thread left, cos when you pull the wheel, you dont want it to smack you in the head, now pull bitches, lol.
removing airbag, cant help with that part, id be careful tho, they would hurt.
