I straight cut mine but did box it as you mentioned, I did not install the bolts as described because I felt comfortable just welding mine. The bolts add some support and allow you to drive the vehicle to get it welded if you do not have a welder. You can get as much on there as your are comfortable with really. I have seen straight cuts with no frame stiffener (full pen welds), frame stiffener welded in, frame stiffener bolted and welded, fully boxed in frame, full box + fish plate on outside of frame, etc.
