I just replaced this. I bought 2 off ebay so I would have an extra. It took 2-3 months for the parts to get here from China.
It was not clear from the add that I was buying 2 (instead of 1), so I ended up with 4 and now have 3 spares.
You have to look really closely at how the 2 pieces fit together so you can pry them out easily. I didn't and ended up just breaking the cover apart to remove it. I think it was a bit easier to just break the old part rather than fuss to remove it.
