I didnt cut exact and we havent cut exact on the bodydrops we have done. We leave at least a half in lip to overlap and with a minimal amout of filler and body work it comes out real smoot and strong. Instead of just doing an butt weld. It made it 100 times easier to weld and smooth and keep strong. But as the others said its easiest to cut straight up the sides and just remove a rectangular section out of the middle.
