If you are talking about the interior chrome ones then I have swapped mine over before now,
If you take off the door card then undo a couple of screws on the back, then the whole unit comes off, there is a pin that causes the pull motion and it is on a spring. just push the pin through, and the handle comes off. (mine was quite scratched on a new set of door cards, so I swapped my original one in)
If that's not what you were after then I am sorry.
