Ermm I'm not sure, I've got a spare one so havent taken the other one off yet. But I have had a look at it and it looks pretty simple.
Think there is 4 torx screws in the boot panel then pull it and it unclips, then iirc there is a couple of small bolts or summin.
I remember looking at it and figureing it out its quite easily.
then its just 2 torx screws holding the lock surround on
I'm really contenplating (sp) wether to do the bump strips aswell but leave the front and rear bumpers. whatcha think?
