Chop
Looks like you got a great start there. If this is going to be your first chop, I would do the top first and get that lined up before you do your doors. Its way easier to fix the doors than the top. Also you may want to run to Harbor Freight to pick up some metal clamps before you make a total mess of you sheet metal, you can check my build I have plenty of pics of them. Remember its not a race, slow down and really think things out before you cut and start welding your project, it will turn out tons better. There have been alot of what I call latest and greatest builds on here that start off strong and never get finished due to lack of planning. Good luck with your build.
