Paint & Body Work - Need help finding Toe/Firewall Extension Panels (78'-81 Camaro)

I am restoring a 1979 Camaro Z28 that I had found sitting in a field and need help finding the panels that go from the end of the floor panels into the firewall. I have searched many sites but I cannot find any other panels besides the floor panels themselves. Has anyone found a supplier that has these panels or did you just hand form them???

Here are some pictures of the panels (NOTE: i didnt install that floor panel on the driver's side, the previous owner had)

That pannel isn't being reproduced. I've hand formed them from sheet metal, an old door skin and an old gas tank. If you look around on another board (pm me for a direct link), there is a fairly recent topic about this. Someone found a gas tank that is close to the correct shape. I'm going to be doing a 78 TA this summer and will proobably run into this problem too.
