Here's an update:
I was able to bend the SS's to form the wishbone. It took a couple tries and a couple wasted stays but finally got a nice bend with no kinks or flattening (or very little anyway).
This is the second wishbone stay I've done and I'm pretty sure there's a better process to ensure it all ends up aligned and symmetrical but I just go at it the best I can and pray a little bit.
You can see in the second picture the mounting plate for the centerpull brakes as I make sure my new posts will be positioned relatively squarely upon the SS's. *If* I get this to work, I think it will look very sleek and clean.
