Seems like it would be much stronger if you welded it all the way around the top and on the inside, instead if the tabs. I think a lot strenght comes from tieing that box into the orginial arm. I know it's kinda hard to weld the inside. Just a thought.
Every time I look at your pictures I want a new camera.
Never mind.
I looked closer and it looks like you did weld it.Da
