My Dart Swinger Project!

Ok here are some pics Its already getting surface rust on the areas I was grinding on yesterday. I still have to grind down all the brackets
@moparmandan you can see where I started the pipe cutter on the small end I made about one lap before it became impossible to hold do you think this will weaken it if I cut the other side instead? Can I go over that spot with a welder and fill it back in? It's not very deep maybe a 32nd or so
