I wouldn’t worry about it being level more that it fits. I’m glad you used the 2 piece. Last year I bought the Spectra heavy gauge version. No complaints about Spectra it’s just that the 1 piece are more designed for new work not adding. I had to cut them apart, refits the sides as I didn’t want to make any cuts in my very solid floors. I used weld through primer. I would not use it again. I felt it effected the welding making it harder. When I was done I used 3M cavity wax with a wand kit to get inside the boxes for rust protection. Check my thread started posts if interested.
Where your angle finder is, at some point gussets were available to add more support. When I was done with my car it did feel tighter but more what I noticed was what I didn’t notice. The unibody seemed to be quieter. I don’t hear creaks and groans and my car was a very solid car to start with.
One thing great about getting older. A life in prison sentence is less of a deterrence
