Here is the best I can do without pulling door panel...
Viewing top of door facing forward at mirror... can just make out front channel on left under weatherstrip, about even with outer edge of belt molding.
Mine is screwed to a 'hat section' bracket that is almost touching the inside of the outer door skin... yours looks like a sheet metal screw holding it to top outer skin lip?
Second one is above mirror pointing almost straight down at channel...
