Does anyone have any advice on how to refit the steering wheel on an air bag model?

When I tightened up the steering wheel probably too tight (i didn't know I could do that) and then it broke the rotating switch thingy, when I turned the wheel.

Now I need to get a new switch (£90 odd!!) and try again.

Does anyone have any advice how to do this without breaking it?

I've lost my haynes manual and torque wrench at the moment! sad.gif
