Repair to left-rear shock tower

As I was re-assembling the pan I discovered the nut inside the left-rear shock tower was gone. Not sure how that happened. As these pictures show, I had to cut the shock tower open, find a nut from the nut bin and then weld it in place. Interestingly, there was a holder for the nut, a kind of flap bent over in support. My nut didn't fit exactly but I welded it in place anyhow. Once in place I then welded the opening closed and cleaned it up for paint.
