Hey, just finished this job. It's not that bad actually. GM giveth, and GM taketh away. The take part is the cheap-a$$ door handle, the giveth part is how easy that cable for the internal door handle re-clips in with that plastic part that holds it in place while you put stuff back together!
Thanks to all in this thread that contributed to making it easy. If anyone's looking for a driver's side door handle (chrome), I have one epoxy filled and for sale (check that forum), and if you're in the Toronto area I can give you a hand.
