What I thought was a break appears to have only been heavy rust. It was in one of the corners but now I can't even find the break because I cleaned the rust up a lot, not completely, but I washed with Brillo pads mostly and did a little Naval Jelly. Any way it may still be broken but I can't find the break. I have to wait til I take these parts down again and I'll look at them more carefully.
But that is a nice repair you did.
