ya you should use your old one you never know if the one you get with the steering wheel would be good some people. To rip people off will have ones that have already been opened or activated with an accident. And just cut the bag out and stuff it with newspaper shreds or paper and seal them up. belive me i work at a body shop and seen that a couple times. so if you ever get a new steering wheel with Air bag you should get it checked by pro or use your old one. unless you buy from a company. than if they do do that you can just sue
