Broken connection between key cylinder and ignition switch

Broken connection between key cylinder and ignition switch
I have a 1995 F150 4.9 automatic. One day the key cylinder quit working except that it would move against the spring load into the start position and then come back into the run position. Once in the run position it would rotate freely without having any effect on the operation of the vehicle, i.e., I couldn't stop the engine from running. Well I finally figured that out--I pulled a 50 amp fuse that resides under the hood. Unfortunately the ignition switch was still stuck in the run position, so the battery would have drained down had I not disconnected a cable.
What I have done so far:
I replaced the key locking cylinder to no avail. Same symptoms continued.
I pulled the ignition switch off of the steering column. It works fine. I can manually click it through all the required positions using the post that sticks out of it, and even start the truck by holding the post over against the spring loading.
So it appears that the key cylinder must be good (it's brand new) and the ignition switch is good (it works the way it should), but the two aren't connected anymore. It seems it would be easy enough to check the rod that connects them, but I can't figure out how to get to it. The steering column is wrapped in steel--for theft prevention I guess, but it's making repair a pain. How do I replace the broken rod?
Any help out there?
Thanks.

Go to this site:
Steering Column Parts, Replacement, & How to Instructions
It used to be Stolen and recovered.com
You can download exploded views, and purchase instructions and parts there.
The part you most likely need to replace is the upper Ignition Actuator (#3E723 in the diagram). It's the plastic rack gear that the key cylinder pushes on. It connects to the Lower Ignition Actuator, which pushes on the pin on the ignition switch. The connection between the two actuators allows for tilt columns. Ford used the same parts for tilt & non-tilt columns.
I had to do the same thing last year, and their instructions were good.
Good luck!

I just found the instructions I downloaded before they changed the web site & started charging for it.
Email me & I'll email back a pdf...

Well, thanks to Phydeaux and the file he sent me, I got the steering column apart and found the broken piece.

Now I just have to get the new piece or pieces (although everything else looks fine) and put it back together.

$16.73 with tax... and hours taking the old one out and putting the new one in. Not done yet. On the other hand, I'm retired and only work part-time as a substitute teacher when school is in session, so I have more time than money... The broken tooth was part of the problem--the pin falling out was the other part.
