Will the doors from a EF Fairmont fit a EF Falcon without much work,ie are the outer door trims different and does it matter if the windows are electric or manual.

are you talking doors or door trims? yes they will bolt up, the door trims will fit, and yes auto or manual will make a difference... you may require a hole in your door trims to fit the manual winder through

you say outer trims? then about winders... confusing much??

doors are the same, the only thing that varies is the trim and manual winder or not.
