If you look at your control arms, it will be attached to the chassis side by 2 pivot points and one on the suspension side, probably. I have no idea, never looked at lancer suspension. Maybe like this:
You remove the nuts and bolts that hold one to the other and the arms should pull out with some force. Then go to wrecker and get some arms and put them on the car.
It's rather basic and you can figure it out if you look at it.
If that sounds too hard, just truck the car to a mechanic/suspension shop and let them do it.
