Nessa3000

Newbie to this forum My beloved Lekky IS200 has a few problems at the moment. One is the left hand side mirror has crapped itself, it constantly makes that turning in/out stuck sound. It won't turn in or out either. I've found someone on FB who has a spare side mirror, but his is a 2003 model, mine is 2000. Will I be able to do a straight swap or are the parts/wiring/shell/etc different? Thankyou for any advice offered.
