Hi, if you take off the side that has the trim on you will find that the trim No is the same as the side that has no trim, it will be No?????? (L) No?????? (R) the trim is easily removed & replaced as the clips insert into plastic inserts, as said, under the bonnet or the door pillars the paint code will be there, make sure you give all the details on the paint code intern getting the correct painted trim, there are many sites to look at including EBay, with postage you are looking up to £20 If that as the thing is only plastic after all, a bit of a tip when you replace, just add a bit of blue tack or the likes to the edges of the trim, this way you will not loose it.
