Just did this and thought I'd chip in my two cents.
If, like me, you found this thread first, the OP mentions an original thread. Tons of good info there too, some of which might not be here. Long link this time:

Random tips that bear repeating or saying another way:
- using an exacto knife helped with getting through the black tar holding the foam in place
- there is also a holding clip near the exact middle of the door -- should be a straight pull to dislodge
- replacing the new carrier into position was kind of a three stage process. One stage is getting the getting the carrier almost vertical inside the small door opening (heavy cable side towards sky), then two, arcing the cable end towards the door lock end, while going high enough to clear the door lock mechanism. Third stage was final positioning. This was helped by having the phillips screw in place and ready for final tightening in outer door notch.
- putting the door handle on again for the plastic twist and lock portion was helped by holding the carrier's movable flap "open", either by pushing on the inside with a screwdriver handle, or on the outside by holding the "hook" that is on the opposite side of the handle.
Sorry if that is wordy, but man, did I waste time doing the repair for the first time for lack of understanding the process.
Next problem for me is as above poster, the key lock tumbler isn't lining up for the hex head screw. I'll try moving the black plastic outer protector out of the way and see if that helps in threading that screw correctly.
Thanks all posters before me.
