I actually have switched my stalk a couple of years ago, the process is fairly easy:
- unplug battery,
- remove airbag,
- remove steering wheel
- remove plastic cover for the steering column and I think there are a couple of bolts to release the stalk itself.... That's the high level list I think.

Hopefully others can give their input on stuff that I missed. Good luck
