Managed to get this done yesterday and took some photos.
Was easy to do took about 30 mins taking time to do it.
Pictures of the old one split at the top


Flip the plastic cover under handbrake, to see two torx screws

Removed them then lift the gaiter and plastic holder

cut the old zip tie off.

The gaiter is then held in with a white plastic clip, pull the gaiter off from it and then fit the new one in the opposite way. The hardest part was pushing the gaiter into the white plastic clip.
all done
