Broken Ignition Actuator Rod Part
I really need your help. Inside the steering column, at the top of the actuator rod, there is a part that pushes and pulls the actuator rod. This piece is quarter-arc shaped, rides in a guide on the right side of the steering column, and some sort of guide on the top of the column. I say "sort of" because this second assumed guide is missing. There is a broken-off stub that comes through a plate in the steering column, but the rest of it is missing.
What I need to know is what is the part called and how do you get the old one out and install the new one? My Haynes manual is no help. It talks about the lock cylinder and the ignition switch, but nothing in between. Any pictures or shop-manual diagrams would be a lot of help.
