I self-installed some new leather seats in my GT, and after many hours of work, at the very end, I managed to put a couple scratches on the very bottom of the vertical metal spoke of my IUP leather-wrapped steering wheel when putting the driver's seat

. I managed to find a new wheel on ebay for cheaper than what Ford wanted, and I was just wondering if anyone here can give me some quick advice on how to replace the steering wheel, so that I don't screw anything else up in the process. Mostly I have no idea how all that works with the airbag and whatever else is in there.
Also, I've seen IUP wheels scratched (and dented) worse than mine go for over 130 bucks on ebay, so I figured I'd just sell mine there unless someone here is interested. If so, just let me know and I will get you some good pictures of the damage.
