yeah the hardest part is reconnecting the 2 metal rods when fitting the new handle. be careful not to damage or lose the white plastic cup that sits on the end if each rod. they're needed to keep the rods conected to the handle. also you cant get to the nut behind the handle if the window is down so make sure its up (or if you go to a scrapyard that the window isnt down, i had this problem and had to destroy the window to get it off).
the clip to release the lock is a small circlip, it pulls off but i found it easier to push it off from the other side using a small flathead screwdriver.
also note, you can fit any handle on any side of the car, so when you go to scrapyards you dont need to find a good condition driver's side, any good conditon handle will do. just turn it upside down and by magic it can be fitted to the other side.
