I am not sure if there is a tech article, I am new to the site, I just got my IDI. FYI it is also a 93 with tilt column. About a week after I got it I lost the only key for it and had to replace the ignition switch. Luckly my buddy who runs a towing bussiness with all ford trucks is a pro at changing them, it took him 20 mins. FYI before that my ignition switch was getting sloppy aswell I could turn the thing all the way around without the key in it. So I was starting it with just the key for leverage.
Here is what we used and the basic process. Keep in mind we did mine on the side of the road.
Tools:
Cordless Drill 14V
Sharp Drill Bit Set ( I forgot the exact size)
Small / Medium Chisel
Hammer
Screw Driver
Process.
You have to remove the covering on the bottom of the column. You should see a pin that is in a hole, holding the ignition cylinder in. You have to drill that pin out. Then use the chisel to remove the rest. Then you should be able to remove the cylinder, it might take some prying though. Once its out you use the chisel to make sure the rest of the pin is out. Then slide the new cylinder in, use the hammer to put the new pin, and you should be set. Since yours is a 93, you can either take the door locks out and get them rekeyed to your new ignition key or you can just use your old ignition key for the doors, since I am assuming you still have it and didn't lose it like me.
The process is a little mystifing with out seeing it or doing it, but really isn't that hard once you get into it. I hope that helps and maybe someone else with have more info or pictures or a tech article for you.
