Bus Depot shows it as:

Ignition Switch
Various applications (see details) $10.95 171905865

It's a pretty straight-forward job.  You need to remove the steering wheel
and the steering wheel lock assembly to get at the electrical component that
needs replacing.  Remember to unlock the steering wheel before removing!
