Long ago I took mine off and replaced it. Minor snafu happened but too hard/time consuming to fix the sheet metal. Got a new one and had it painted, then did the swap myself. Removing the wiring from the hatch is a PITA but otherwise not too bad. I do not recall anything other than usual tools required. (Probably need a torx set.)

EDIT: Here is a thread I started at the time. Not many pics as I was very busy with work and a home reno back then.
