Re: Steering wheel badge
The only chance you have to remove the emblem in one piece is if you have access to the back of the airbag piece. The winged emblem is glued and it has pegs that go through the airbag piece.
Once you have it off, you will need to fill the recess the wings fitted into, if your new piece needs to fit on a flat surface. Be warned the top surface above the wings is not aligned with the surface below the wings, and filling and sanding is very difficult because the material is flexible.
Good Luck!
