1984 4 speed steering column help!

[72blu]

So today on the way to work I had the windshield washer/turn signal stock switch completely break on me. This isnt my first time tearing into a GM coulmn so I dove right in and started tearing it down to get access to the switch. Unfortunately for whatever reason I cant seem to find any information regarding how to remove the upper column housing on a 4 speed column. All the videos and posts ive followed show people breaking down automatic columns were all they do is remove the final four screws that secure it to the base and it simply seperates. For whatever reason mine wont separate even after ive removed the four screws.

Any help is appreciated and ive included a picture of the switch that broke on me
