It's actually a plastic coated steel collar.
What I believe it has is 2 holes offset 90 degrees from each other.
A shop-made tool is used, I'm not sure if the instructions to make the tool is on the 126 disc or not. It's a U shaped piece of wire (if the instructions to make the tool can be found it would give the wire gauge, it's not as thick as coathangar wire, but thicker than mechanic wire). The wire is bent into a U so you can insert the wire into both holes at once, however you need to use a grinder on the wire on ONE side to taper it, on the INSIDE of the U (on the tips of the wire, the part going into the holes. The tapers go into guide holes and pull in 2 retainers which hold the cap over the steering lock (around the cylinder). I'm pretty sure this is the style used on the 126.

IF there is only 1 hole, it's a little easier, just need to find the right gauge wire, just a normal cut-off end (no tapering in other words) and it's inserted into the hole, and just push down hard and that releases the retainer.

With either type, the cylinder has to be in #2 position, but it sounds like you have the cylinder locked in that posion now anyways. It can be pretty finnicky though, so hopefully it's lined up good enough. If the wires won't go in very far, it's a safe bet it's not close enough.
