replacement sheet metal for SWB beneath battery?

I would like to reopen an old thread as the problem below is now mine and many others now and in the future I would imagine.

I don't know how to link to the original threads so would be grateful if somebody could

Wondering if there is replacement sheet metal available for the exterior panel located beneath the battery. I am not talking about the pan. The portion I need is part of the wheel well panel, but I only need the very bottom. I do not want to buy a whole wheel well panel. Hoping there's something out there that would save me fabrication time at a reasonable cost. For example, I seem to recall the lower portions of fenders being available. Maybe the same is true for this piece?

I have tracked down Damon at Series900 but he has gracefully declined to make me some Any help would be much appreciated
