Okay, forgive me... I wrote 14 thinking it was next to the correct part... But everything else I said was correct.
I'm pretty sure I'd know the difference between an 18" part and a 60" part... Look at your trim, it may not be sold in separate parts, but the rear section is a removable piece. I have the front section, but it is unusable- if you want me to sell you a part that is scratched and bent, I'd be happy to steal your money- but until then, I don't have what you are looking for...
