Mirror Problems

I'm having trouble adding the gear door animations for the plane I'm making. It's not that I don't know how to do it, it's just that the wing I'm adding it on has a mirror modifier on it. When I swich to edit the wing, the mirror modifier turns off, so I can't line anything up accurately. Does anyone know how to edit the object without turning off the mirror modifier? ??? Or would it be easier to set the 3-views back up and redo the whole wing again? ::)
