you're so cool and trendy, you used "failed"
so, lets go into your superior intelligence on frames..... this picture is what it replaces, just for reference.....
the existing frame is what, .100" thick? 2.5x4 box section with no welds in that area. The new frame is .120" wall 2x4 box that has been butt welded and welded flat off the vehicle, not vertical and that just so happens to be the worst weld on the truck and it was not ground down to cover it up to sacrifice strength.
There is no internal bracing except where it splices into the stock frame. what you dont see is the fact that the b and c hoops on the cage are also tied into the frame. The angle on the joint is flat enough that pulling it apart at one end is highly unlikely even though it doesnt have fishy plates anywhere on it and it doesnt meet your e-engineering approval.
If it ever shows signs of failure I'll be sure to post up and admit you were correct, until then, just remember not everything needs to be built 5 times stronger than it needs to be.
