C220 Steering Wheel Removal

[Okiebenz]

Does anyone know the torx bit size for the 2 screws that attach the horn/airbag to the steering wheel of a 94 C220. I need to remove the wheel to get at the combination switch and also to remove the instrument cluster for replacing a bulb. I probably will have to make or buy a special long shaft torx driver since these are in a deep recess and I want to be sure I have the right size. In what appears to be an affront to the DIY world, MBUSA has chosen not to publish any of the manuals for this model even 8 years after production start.

Thanks,

Okiebenz
