Sorry, probably my bad wording! I know the part itself is plastic- what I meant was that in a couple of sets of instructions I've seen for installing them, people have mentioned metal clips that need to be removed and replaced, but I've no idea what they mean!?

The metal clips that hold the trim into the A pillar.

Ah OK, are they easy to fix then?

Just got a quote from my local dealer of £37.37 for this and the in-dash cup holder...quite appealing, just need HR to finish p**sing around with paperwork and let me start my summer job...
