I just did mine today. Thanks to those who figured this out and their excellent photos. Two things can make this a bit easier.

1. Drilling out the steering lock pin can be a pain due to its location, alternatively one can drill or grind a path from the hole where the pin goes into the steering column to the end of the sheath. That allows one to remove the ignition lock console without the difficulty of drilling the hard steel pin itself.

2. There is no need to remove the tumbler at all. One just needs to remove the ignition lock console open the hatch in the back of it and remove that nasty pin and spring and everything will work fine.
