Basically it's very easy to get the door cards off, 3 screws , 1 for the door opening handle escutcheon, 1 near the door pocket, both Phillips or Positive, then a torx one by the door pull, all behind plastic covers, then remove the cover for the door mirror, then using a trim removal tool (better than a screwdriver) release all the door card retaining clips, then lift the door card up. Best to remove the wiring connectors for the window switch and the electric mirrors ( remember which way the window switch connector goes on the drivers door (I managed to get it wrong once !). Some of the door card clips will break, I've found the yellow ones for earlier Ford's are generally reusable and that's what I used as replacement's.
Don't think I've missed anything, but I've written this from memory.
