My problem is the key is seized up and won't turn. The shifter is locked, but the steering wheel is not. I have removed the cover trim fro the radio which gives me some access to the ignition housing, and I have removed the two mounting screws - so the housing is loose, but everything is still hooked up and I cant pull it through the radio hole. Also, because the key won't turn, I am concerend I won't be able to remove the shifter cable due to it being locked in. I have a replacement housing in tact from a wreck parted out that appears perfect. It has a key that turns so I have the complete componet ready to install. My main question is how do I get the old housing out and release the shifter cable? Thanks in advance for your help!

It would appear that I need to be able to turn the key to make these instructions work. I made it pretty clear the reason for changing out the ignition is because the key doesn't turn.

So I'm not to sure the answering tech really read my question, or understood why I needed the help.
I don't know what or where the left sound insulator is, or why it would be a factor. Also the instructions mention drilling the housing to get the shift cable off. What exactly am I drilling? A sledge hammer sounds like a better remedy. Any additional help would be appreciated.

I did read you question and did understand it,you have to drill out the side of the lock cylinder to remove the ignition cylinder to release the cable that goes from the shifter to the cylinder housing.here is where you have to drill,

drill out hole #1 and remove the ignition to release the cable and to replace the housing,if its easier for you just replace the cable and the ignition housing and cylinder.might be easier to replace as a set,I replaced 6 a week on these vehicles when they were new.post back if more help is needed.
