Here's A Little Help
Well you're almost there for certain..........
After having removed the Inst-Cluster to provide access, use a long reach needle nosed pliers to remove the switch contact (careful of the wiring).
Then there is a hex head screw which stabilizes the column lock & keeps its position properly center. A 1/4 drive w/ 1" extension works great! You'll find it with a inspection mirror & a light.
There is also a "ARRESTING/LOCKING TAB" which you will find by running your finger around the lock barrel. Once found, depress & release the lock from the steering column. I find the pick from a Stubby Hook & Pick Set works best for me!
Needless to say, ensure that the NEW switch is aligned correctly & works by re-installing the IGN Lock & Barrel before you start to re-assemble the Instrument Cluster. "Triple check the re-installation of the LOCK-TO-COLUMN & ARRESTING TAB!!!!!!!"
The wiring for the IC indicator lamps should be marked 1,2,3, etc which correspond to the positions on the Cluster Back Plate & of course the other connector plugs cannot be mis-positioned! Test the lamps & if okay, you should be good to go.........

1st things being 1st, what you need to do is:
1)Remove negative cable from battery
2)Key inserted
3)Turn key to position 1
4)Insert special tool (use a paper clip) inserted in the slot to compress the lock cylinder spring (do you have 1 slot or 2 in the cylinder bezel?)
5)Do Not attempt to remove the key or the paper clip
6)Twist / Turn the black cylinder cover to the left. As this component threads OFF, the Ignition cylinder & key will be removed along with it!
P.S. If you are having a difficult time locating the Arresting Pin while trying to remove the steering wheel lock, try a "THIN FLATHEAD" screwdriver between the dash-padding & the black upper surround of the steering column. Following the line of the Ign-Switch towards the steering column it should be between 90 - 180 degrees!! If you have already removed the hex screw as I'd directed you to, the the entire switch can spin a bit up & down. A bit of upward pressure on the switch (where the connection block has been removed) towards you, will cause the entire lock to rotate when you hit the arresting tab! Wiggle & pull to your right & it comes right out........

working it
Thanks for help, I'm going to work on it tonight. I do have a two slot ring, looks like tool needs to be inserted at same time to allow ring to be unscrewed.

still working on this. I did get ignition out without breaking anything. Have yet to remove black cover which allows key tumbler removal. I understand the concept, just dont have the touch yet. I did find another link that shows some great pics, good luck. http://www.peachparts.com/shopforum/...d.php?p=769549
