Hi Jordan

I was examining my 2C1 box and if I had to do the side pockets I would do this.

measure carefully the size of the indentations and the depth..... about 3/32 or the tickness of the metal if you were using 14 guage.

Center the outline of the indentation on your new 16 gauge vertical brace.

Cut as outlined in the attached sketch.....MAKE SURE TO LEAVE A GOOD PIVOT POINT...... at least 1/8 uncut.

Think of a damper in a chimney..... you should know about dampers......
Pull the upper 48% out by 3/32 and pushing the bottom 48% out an equal amounts.

Weld from the back first to fill the gaps......then the front and sand smooth the front visible side....... make sure yor behind welds are solid as they will carry the torque of the hoops.

Now I must point out that I have not tried this but it is how I would tackle it.

Good luck and post us some pictures. No doubt the original was stamped before assembly.
