the thin black plastic that surrounds the driver's side mirror is cracked and broken. i think i've identified the correct part # 1K8-857-601-A-9B9 for my 09 lux 2.0 tsi. before i start (or not start) this my question is how much disassembly is required to swap this out? can i just pop off the mirror and unclip the old bezel then clip in the new? screws? any best way to pop out the mirror? thanks.
