I'm looking for a different steering wheel and was curious if the 2nd gen ISx50 wheel would fit in our IS300's. I'm looking to gain the audio controls. It doesn't have to be the is350, i wouldn't mind any other lexus wheel with the shift controls (since i have e-shift). I know that Lexus went from single stage to dual stage air bags (what ever that means), so some of the older wheels won't fit on the newer ones. But i'm not sure what we have.
