Since bobby's m/y 80 sii column is the "last" version, it's somewhat different. Some component level interchange is possible.some is not. The parts list defines the cut point for "which" column is used in what chassis number.

And that is in regard to the "locking" version of the column used in Scout II and only the '74/'75 pickalls. There are variations in the saginaw steering column assemblies over the years, both regarding the tilt version and the none-tilt. The parts guy used the LST to go against the parts book (microfiche in those days) to find the correct parts. The first thinig they asked for was the LST (I did not know what it was). I had my t/a serviced at the dealer where I bought it. Maybe the cancelling cam / snap ring are the same for all Scout steering columns maybe not. I have no idea, but there May be slight variations in the steering columns between different year scouts maybe diesel scouts are slightly different from gas scouts. So, putting it back together as taken apart is the best plan.
CHANGING IGNITION SWITCH MANUAL
The service manual May not be showing you the "correct" picture. To find what your vehicle had stock from the factory (before po "improvements"), you need the parts manual for the vehicle along with the LST.
CHANGING IGNITION SWITCH MANUALS
The service manuals are a "guide" for fixing / repairing an IH vehicle - not the end all / be all reference guide to every "variation" that exists among a large group of IH vehicles. Your statement (above) and the statements of a couple other people plus my experience with the rear brakes (just looking) of my 1210 t/a leads me to believe that It was under basic tech questions and titled replacing ignition lock cylinder. It was very useful or I would have never found it. I found another thread on this forum that had pics to locate the hole. There is an access hole right beneath the top right, cast screw hole. You will need a small bladed screwdriver to get to the release. I was able to pull mine loose enough to get access to the release for the ignition switch cylinder.

After that, use great care in pulling the turn signal cam out so you don't break any wires. The retainig ring on my truck was a simple wire type and I was able to remove it simply enough with two small straight screwdrivers. It's called a steering wheel lock plate tool remover and installer. It was only $11 dollars and should be available at most auto parts stores.
I tried several times before admitting defeat to the spring and buying the tool. I had to purchase a tool to press down on the preloaded spring in order to remove the snap riing.
