Late 31 Firewall Question

[53OlderThanMe]

I recently acquired a very nice late 31 firewall for my Roadster to replace an aftermarket hot rod one that came with it. After installing I was thinking it must have come off a channeled car as it appeared to be missing the bottom side section on both sides. I found a picture of a whole late 31 cowl online and now see I am instead missing some part of the subframe? Can anyone help me id the missing portions I have highlighted on the photo in red? Specifically what are the called and are they reproduced?

Thanks
