I did mine a while ago and it was straightforward. Remove the carpet type trim panel from inside the tailgate (quarter turn plastic clips and a couple of torx screws for the handle). Its then a case of removing all the bolts that hold the panel on. Take a look at your replacement one to get an idea where they all are. Look out for the ones which are hidden and accessed through a hole in the inner skin. Once they are all out it comes of without any force. There may be a bit more detail but thats how I remember doing mine!
