Concerning the 2003 steering wheel, I have good news and I have bad news, the good news is that Dal Slabaugh of Van Devere sent me this
"on the steering wheels, gm only shows in pewter (gray) on
both vehicles. your cost on the leather wheel is 224.86, on the
plastic wheel it is 113.41 each
no graphite color is shown on either,
let me know
thanks
dal"
The bad news is that the airbags are not compatable and when I called my local dealership to ask about the comparison they stated that the new airbag would run from 600-1000 bucks which I don't think is worth it for a steering wheel. So, unless you have a hookup at a dealership that will let you swap airbags or something, it's just not worth it.
