Is this panel available aftermarket?

I needed them when I was restoring my ‘69 cuda and I ended up making them myself. I still have the patterns but they are marked up and don’t remember if the patterns need to be modified. My car had fenderwell headers at one time so those two braces were pretty hacked up. They came out nice and when I brought them to my body guy to install he didn’t believe me when I told him that I made them.
