Air-bag wheel removal tool?

[wmc_sr20 at bellsouth.net]

Hey Y'all...

Trying to remove the air-bag equipped steering wheel in my '91 NX.

Know where I can get a tool to remove the "tamper resistant" bolts?  It's a
Torx T50 that I already have, but they put a damn stud in the center of the
thing so you need a special hollow shaft Torx bit.

Do regular parts stores carry bits for these, or is there some other
work-around?

Thanks,
