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? 

What I ended up doing is attaching the original wing to the mirrored wing to create a single non mirrored wing.  That worked for me.    It's probably the hard way though.
