It is easier than expected. No screws, just pull out the remainder of the glass and then take a pair of pliers and grip the plastic about an inch to the left of the protruding plastic clip at the top. The whole unit just slides out with only a little force - not even any retaining clips to push in. Sliding the replacement back in also easy although I was waiting for a click to let me know when it was in securely but it never came. Looks like it's in far enough though.

Just be careful pulling out the glass (recommend you only take pieces from the top left to allow you to access the plastic) as it's easy to scratch the bodywork as it's very tight
