Bracket on firewall

[Klattu1929]

What is this bracket on the firewall just above the steering column cutout, don't know if I need it or should remove it and fill the hole. Also, my car is titled as a '29 but the date stamped on the firewall just above the seam for the gas tank is 6/18/28, engine serial #makes that as April of '29, so I may have a mixture of different cars.

Current build on my chassis, ran the engine, sounds pretty good, drove down my driveway sitting on the home depot bucket, had to use a light switch for my ignition as I don't have a proper switch yet. going to install shields on each side of oil pan next. Good times.
