Yeah, man, I cringe for you my friend, this is basically classified as being made from "unobtanium".
I think the best bet would be to find a used piece in a good shape, and it looks like you may have done just that!!!
Man, this reminds me of how long I looked for the wheel well lip trim (fender lip) for my coupe. Heck, years...but while doing so I scored two sets of NOS trim for the 4-door rides, but ZIPPO, ZILCH, NADA, NIC NIE MA for the coupe! Every time a potential lead went nowhere I reminded myself of the last time when I had asked the local dealer to look up the avilability of the part. Couple came up, both were around the $50 price range, and I thought: "ha...like I'm paying THAT much....give it some time and I'm sure you'll be looking for me to buy at MY suggested price"!!! What was I thinking???
