Firewall Extension
 

I do not know what this are is called on my 1930 tudor sedan. Here are two pictures of what the front firewall extension area looks like on my car and a picture of what it should look like. Where can I get just the part I need to fill in this area and what is this part called?

This a common area for this area to break out. My 30 coupe was broken out similar to your's. With a little patience and trial and error and MIG welder you will be able to fix this and no one will ever know. Square up those broken edges and get some sheet metal the same thickness. I used some construction paper to mock up the initial shape then transfer it to the sheet metal. Tack your patch in with the MIG in several place's not to much in one area,let thing cool so the metal doesn't distort. It is called a subrail extension but to use this repro part it would be more work to install it as it not made very well. your damage is not that bad try repairing it . I'm not a body man if i can do it so can you.
