Inner drop panel for right rear

Hi all.

Working on my 1965 Barracuda formula s, very soon. Tring to get some of the weird parts before I start. Any you gurus know if the inner drop panel on the right side is available? The left was done by previous owner. I just need to know if I can get one, or am I going to have to fab on. Thanks in advance

I now know it is called the trunk floor extension
