I'm Neal and I am here to assist you. Only accept when you are happy with my assistance. If I can't help I will open your Question to other experts.
Have you tried the scrap yards? You should be able to find one there, they are not a high demand item and are usually still in the cars.
Yes that is not something you see in the aftermarket. I don't even know if they are available through the dealer. It might be worthwhile to try some more scrapyards even if they are further away a few phone calls might pay off.
I do know you will pay through the nose if the dealer does have them.
