If anyone else has some input on this please feel free to chime in.
I have been following your instructions on replacing the ignition cylinder in the column of my '71 and am having major problems and hoped you could help. Let me start by telling you what I have done. This whole process started when I went to replace the turn signal switch. I disconnected the switch from the harness and unscrewed it from the inside of the column. I the proceded to pull the wires up through the column and low and behold the connector turned sideways and got stuck. Now I know if I would have read your paper on this it could have been avoided if I would have taped the thing up so it wouldn't get stuck but I didn't see the paper till after the fact. :-). Anyway I thought that the only other way to get it out was to disconnect the sleeve that the ignition cylinder was in. This worked however I have not only pulled the rod loose from the gear on the end of the ignition cylinder but also that rod that has the spring on it fell out and I am not sure how it goes back in. But for now let me get back to the cylinder. I followed your paper on inserting a flat tool into the rectangular skinny slot and pushing the spring loaded tab in for the cylinder to release. However this is not happening for me. I do think that someone has replaced this before so maybe if it is possible they did it wrong. Being that I have the whole sleeve off and in my hand I have been able to look at it from every angle and just don't see a spring loaded tab. Can you help me with this please? Also can you give me some advice on the following questions.
1. Do I need to take the ignition cylinder out to get the teeth of the rod and gear to mesh correctly?
2. The rod on the back side that has the spring on it that I mentioned earlier. Does that spring compress a little and then the exposed part of the rod under the spring fit up into the "U" shaped peice attached to the ignition rod and rest between the inner portion of the bottom of the rod and the bottom side of the spring, then slide up through the whole in the sleeve?
Thanks for any and all help or advice that you can offer.

1). My latest paper posted at http://www.corvettefaq.com is entitled Std Column Disassembly & Repair Paper #1 and has a revision date of 20DEC2002. On page #8 of the paper there is a rather poor scan of a housing but it shows the vertical slot where you need to depress the lock cylinder locking wedge. The slot can have a thin die cast skin covering it so you may need to break through the skin in order to depress the locking wedge.
2). The pointed end of the lock bolt sticks up toward the steering wheel. Then the spring, then the lock bolt rests in the U-shaped receiver on the rack. The teeth on the rack are also pointing at the steering wheel. The rod attached to the rack extends down to the ignition cylinder.
You can imagine with the rod and rack installed in the column, you will find that the lock bolt is spring loaded up toward the steering wheel. When you put your key in the lock cylinder and rotate it to RUN; the plastic sector will rotate and move the rack away from the steering wheel and the rack will pull directly on the bolt moving it away from the steering wheel and unlock the steering.
3). You normally have to have the lock cylinder out of the housing (cylinder) so that you can rotate the plastic sector (gear) far enough to feed the rack back into position. However, you seem to have disassembled the rack from the housing and the lock bolt and spring (rod) from the rack. My question is -- With the lock cylinder still in the housing, how did you get them apart in the first place?
I will scan a couple pages of the Saginaw steering column manual that might help.

Thanks for the help. I do want to see if I can clarify the lock rod though. So the rod rests in the "U" shaped clip that is attached to the ignition switch shaft correct? The tiny spring that is on the lock rod, do I squeeze it upwards and then fit the exposed area beneath the now compressed spring into the "U" shaped clip?
Thanks again for the help and would definately appreciate the diagrams.

The old in-the-dash integral lock cylinder and ignition switch had a small hole in the face where you could insert a paper clip and with the key remove the lock cylinder.
Starting in 1969 the GM function locking steering column requires that you remove the steering wheel, hub, and lock plate; as well as move the turn signal switch up and out of the way in order to get at the locking tab (or the screw - 1979 and later) in order to remove the lock cylinder.
Some people have used a slam puller to shock the lock cylinder out of the dash. This procedure usually breaks the hardened tab that retains the 1969 through early 1979 lock cylinders. As you might guess, slamming the column is hard on the column parts and doesn't do your instrument panel any good either.
BTW, I have just submitted some new updated Disassembly and Repair papers to Terry Rudy's http://www.corvettefaq.com websight. They are Paper #1 and #3 for the T&T Column and Paper #1 for the Standard Column.
The T&T Paper #1 now includes some checks for loose pivot pins, loose tilt shoes, and loose support screws. Also some clarification as to removing and reinserting the lock cylinder into the column.
T&T Paper #3 now includes suggestions as to repairing loose pivot pins and loose tilt shoes. Also a procedure for testing and tightening the plastic tilt joint.
Standard Column Paper #1 now includes a more complete description as to how to remove and reinstall the lock cylinder.
