On to the Right hand side. Hard to see in the picture but this side had a quasi rectangular piece with the round hole welded over the frame.
After cutting the rectangular piece loose you can see the same hogged out hole underneath (a little larger on this side)
Clean up the damage
fab up a patch, back with copper and weld
I didn't get a picture of just the patch weld. in this picture the patch was already welded and ground and I had now welded to fill the area gouged out from removing the old piece, and filling a couple spots on the patch weld.
