[Closed] Headset assembly / installation diagram

About to replace my headset (Giant Overdrive, 490901), which I'm not overly experienced with. I'll obviously try to take note of how the old one comes out, but given the number of parts that are in the box I'd take comfort in knowing I have an assembly diagram to check against.

I've had a Google around but can't find such a thing. Do they exist, or do I just have to be REALLY careful?
