in my moms century, you had to do a whole lot of careful prying, but you could get the panels on the steering column off without popping the wheel.

the videos and jasons tutorial were exactly the same for the century, so being that its the same on that wide variety of cars i cant imagine it would be any different on your car.
good luck!

I have replaced two ignition and two multi function assemblies on a 97 and a 99 Bravada. Did all of them without removing the air bag and not disabling the battery (not recommended). I found replacing the multi-function assembly pretty easy. The key was to have the proper small TORX (I think a TORX 7???) and be able to get under the dash to where the switch plugs into the harness.
I did one of the multi-function assembly replacements in a parking lot at FT Leaonard Wood, and the ignition switch in Kohls store parking lot. The key was to have patience. I did these with minimal tools, the cheap (and small) TORX set that the auto parts store sells was the key tool- think it was on some little ratchet setup.
I am not sure how much if any of this will apply to the Bonnie, but GM often designs these similar.

one nut on the steering wheel. forget the size of it. get with silversurfer he has my old air bag tool that will remove your air bag. the screws that hole that switch on are T-25 as well as the ones for the shroud around the column
