I just finished this job and Dubaday's comments are perfect. Do not use any new part EXCEPT for the broken bunny ear part (Part 1). Even though part 2 looks similar, the new one is slightly larger and will frustrate the heck out of you when you try and lock on the springs. Obviously the paddle is different and had seemed to have and caused a lot of confusion in earlier posts.
Here are the steps I recommend:
1) order VW part from Amazon or EBay
2) order triple square bit set (I stripped one bolt with a T-30 torx that seemed to fit)
3) disconnect battery
4) remove door panel
5) remove metal bar and airbag (you need the room for sure)
6) the rest has already been described well...use all old parts except part 1
Obviously if something other than part 1 is broken then disregard!
