The mirror swap and the addition of the passenger mirror went perfectly. The big hole for the remote cables was already in the driver's door, as was the mounting hole for the joystick. The hard board for the door panels was perforated where the joystick comes through, so a couple nudges with a razor and it popped out.
I think I measured a dozen times before drilling the passenger door. So stressful to drill into something pretty. While the door panels were off, I located and fixed a rattle in the passenger door and then Dynamatted both doors.
