Convertible top molding
 

Hi everyone, hope someone can answer this for me. I have a 2006 Cooper S convertible and the molding/gasket needs to be replaced, at the bottom back. my dilemma is auto parts shows “right” and “left” and technically there is a right and a left, there are three, but I need the long main one in the middle with the lights in it. Could this possibly be referring to drive on the right cars and drive on the left cars? It’s so confusing, it’s a pricey little bit of fluff so I don’t want to make a mistake. Hopefully you could follow this and lead me in the right direction. Thanks bunches!
