Sorry if this is the same image (got bored waiting for the page to load tbh)
4~ plastic, plug type fasteners in the boot-shut
a 10mm bolt and 2 torx screws in each wheel arch
1 (only??) fastener in each side in the bottom corners of the bumper (I don't have these anymore, so can't remember what they were)
The whole bumper sides into a
guide strip (item 13) about an inch below the boot level and a
guide on either side, so if you pull it straight backwards a couple of inches it should (will!!) drop away... get a friend to
help if you can
