1995 Subaru Impreza ignition and housing problem

No sorry it was a subaru liberty. Similar to the outback. I know it wont fit I just need to know how to remove the inside mechanism from its case then purchase a housing from the same model as my car and place the guts of this one into the new matching housing. So again my question is how to remove the ignition guts from its metal case? I know that most need the key turned to acc or so on and then you push a thin screwdriver into the release pin and pull the key to remove the ignition barrel. I cant seem to find this so called release pin. The ignition barrel and housing in question came from a late 90's early 2000 model subaru liberty

Nah dude u dont have to do that man I just need to know how to remove the insides of it. How do I take the barrel out of the metal housing. Ill put some photo's up. The first pic is the outer housing. The second is the face of the barrel/cylinder I want to remove. Please tell me how to take it apart
