Tilt Column question

Hi everyone,

I have a tilt column for a 65 Chrysler. I want ot service the tilt mechanism and do a thorough clean up before installing in my car. The tilt works but is stiff, clearly needs lubrication I can't get the metal cover off the top of column (where the lever and turnsignal arm goes through. Looks like its press on, anyone know a trick to remove this ? Thanks, Tim
