Mine just arrived today and I tried to get the old ones out as well to no avail. In the Sedan the assembly is completely different from the coupe. The honeycomb seems to be a separate piece from the part that's getting replaced, but I can't tell if the honeycomb is one piece or two. I slipped a zip tie behind the top honeycomb and threaded it through to loosen it, same with the bottom, but the middle piece won't come loose. Where are you supposed to put the credit card?
My fender is also plastic.
