range P38 door latch mechanism - repair

hi very grateful if anyone can help with some advice. drivers door handle on my 2000my range rover p38 wont open from the outside. (it works from inside the car). i have tried out a few suggestions on this site but to without any success. Have decided therefore to replace the plastic cam inside the lock mechanism. and purchased land rover part STC3064 from rimmer bros for about a fiver (picture enclosed)...... I am having trouble getting the mechanism out of the door, i have removed the torx screw just inside the door and wiggled the door handle to expose the mechanism, but really i need the whole thing out to work on it... any advice welcome!
