I had to do this with my Evo III ... It is not an easy task ..
What you have to do, is get the door trim off with the door being closed .. Sounds impossible, but can be done.. This was what I had to do with mine...
Once the door trim is off, you need to unscrew the handle and then open the door from the outside, as you will not be able to flick the child saftey switch off while the door is closed... I had 1 screw in the door trim that was v/hard to get too, but with patience it was achieved .. The rest was all clips, and the usual screws for the arm support and stuff...
