nope, the wing does not have to come out.
its not that bad, Ive done two of them.
unbolt the regulater from inside the door, and set down in the bottom of the door. then you have to put the front of the window in the slot first, that will let it slide forward enought that the rest of it will clear.
slide the window into the door and then slide it up the window channel. you have to monkey the regulator around to get the two wheels to get into the track on the window, (huge help to have someone else that can hold the window up while you do this) then you have to fiddle around to get the regulator back at the correct level to reinstall the bolts. get them all in before tightening them down. then loosen the bolts that hold the window track slightly and snug the track up to the glass, this will prevent the window shattering when the door is closed with the window all the way down.
