I'm unsuccessfully teaching myself to make sheet metal things. But here is a tid bit......
Last time I left off I had slid the replacement rail into the passenger side. I used sheet metal screws threw the original rivet holes to hold it together. I'll completely weld it later once everything fits together. Scroll back a few pages if you need a picture.
I figured the next thing to do would be to fix and attach the passenger B pillar. It looks like this.
So I removed the triangle brace.
And I bought some 18g a few months back.
and made a pattern.
I then transferred it to the metal.
and cut it out with these( what a PITA, I need something better)
And started bending.
This was my first attempt.....

Kinda embarrassed.
I did all this all with my vice, a piece of 1inch square tube. a hammer, and the back splash of my work bench. It at this point it needed some refinement.....
