Here is a pic of what happens on the bottom edge at the rear as you work the body line out to match up. I will simply trim this as a long straight line later.
I figured out later that it is best to make most of your welds, but not solid. Wait until after you grind them down the first time to fill in completely with solid tacks. The problem is that when you have small mounds of tacks and you try to aim for that 1 last hole, you end up welding on top of a weld and that just makes more you have to grind off later.
