Continuing hacking and welding the toolbox. I got the top done, aside from some time with the grinder cleaning my welds. And I made a patch that will finish the front wall, but I didn't get it welded yet.
I'll try that technique and try to eliminate some of the ripple in the floor. I'm not too concerned about it, except that it's right in the middle where if you put anything in the bed it pops. I'm definitely curious to see what the muffler sounds like.
