Good job. With the correct procedure this is an easy job, but most people are scared of the process. I did my 04 Expedition a year or so ago when I repaired the cruise control switches.
One other thought...When setting the airbag aside, set it face up. Setting it face down could result in it becoming a projectile if it accidentally deployed.
It is not a hard job, but definitely something to take the proper precautions with.
