Hi Sean, the part number is 51317017021. Google this and see where the best place is for your location. I am in France and ordered from Hubauer Shop in Germany for an OEM item. Just over €40 delivered which was a good price and quick delivery. Local windsceen shop in Grenoble was reluctant to do it in case they broke the screen, but there are a few videos on YouTube on how to do it. I bought some plastic trim tools and something called Goo Gone which is a spray cleaner to remove any adhered bits of old trim. Apparently the channels need to be very clean for an easier installation. Will carefully give it a go this winter after I put the car away for storage
