lock and tumbler/ignition switch questions, 1990 Mustang 5.0

so the lock and tumbler in my 1990 5.0 decided to jam up today, I understand the proper way to take these out is to turn the key to the on postition to access the retaining clip... problem was my lock would not turn so I had to mash it up pretty good forcing it out.

I removed the lock/tumbler assembly, and found that the end piece (the piece which turns with the key) had broken off in its housing between what looks to be 2 brass coloured teeth, and it won't come out!

so a few questions:

1) anyone have any suggestions as to how to remove that little piece so that i can put in the new lock and tumbler and be done with it?

2) if it's hooped, I have no problem shaving the housing off and putting my ignition switch elsewhere in the car, but wouldn't this give me problems with the steering wheel lock? as the stock lock/tumbler is what unlocks it. :headscratch:

anything is appreciated! thanks.
