That crooked ubolt will straighten itself. and when it does, it will be loose and will come apart. With ANY ubolt, after its tightened, you should use a hammer to hit the "u" end side to side, and then retorque to ensure it is as close to 90 degrees as possible. I saw that same thing when I was looking at that truck.
They also had a CUCV that was lifted, and the end of the leaf spring on the shackle was resting against the frame, as if the springs they used were too long. They really dont impress me. Seem like a krylon and tire job with no real knowledge of how to assemble a truck.
