Do you guys know how much a Steering wheel, hub and Airbag go for .. its for a 2003 s2k?

 

Are you asking about factory parts? A factory wheel is (USED) around $100 + Air bag (USED AND GOOD) around $200 there is no hub needed for OEM parts.

After market parts: Wheel around $300 + no air bag is available sorry hub, is around $75 to $150 depending.

There are venders on S2KI like Sam S2X who sell the NRG brand wheel hubs and alike
