Repairing a brass windshield

I'm thinking about how to address a couple of issues on a brass windshield. The first is a crack , the second a distorted hole. See photos.
I'm thinking about annealing the cracked area, compressing the housing to restore the contour of the housing and close the crack and silversoldering the crack after Ving it out a tiny bit. I may have to ream the hole afterwards
I'm thinking about annealing the smashed bracket with the distorted hole and pressing a tapered pin from the opposite side where the hole is still round. I'll support the bracket from below and re anneal when the brass begins to harden.
Any criticism, alternatives, precautions, etc are welcome as moving metal is nor my forte

Richard, I presume the lower picture with the catch lever is a brass casting. That crack is a candidate for silver soldering. The hole has been expanded by repeated folding of the screen. It happened cold, so I would just beat on it to close the split somewhat, do the V trick and have at it.
I presume the hole in the other piece takes a bolt/pin of some sort. Rather than heat and solder, might it be better to drill, thread and plug it with a brass piece and just re-drill the hole?

Others may have better ideas.

Silver solder the crack, heat up the area around the hole, let it cool. Support the bottom and press a long tapered punch into it until you get enough clearance for the bolt to fit.
