Removing Pivot Pin 91 Century

I was taking my steering apart yesterday to tighten the four tourx bolts inside the steering collum and when I got to removing the pivot pins from the tilt I found that one of the pins had the hole pluged with what looks like a part of a bolt. Is there any way that a person can get the old pin out without any damage to the rest of the collum? Thanks for any help. Sandy :confused:
