I have the Euro Tirangles too...if you have them as a replacement part just llok at them and you should be able to tell how they are installed. I have my interior out so all I did was push one of the pins out from the back and then gently pry it out. They are not very difficult, just take your time. PeaceYeah I was wondering about these too. I've got the glossy triangles, but not the b-pillar trim yet.
So it's actually a replacement part, not a stick on thing.. How does the stock part come off? Is it just adhesive? Would be cool if someone had a pic of the replacement part off the car.
