Nope, just logic with trial and error.
A few HUGE ones come to mind. I did post elsewhere on having to get a bunch of different sized washers available for the swing out hinges to rotate on. The bushes and washers supplied were too wide to fit. Grab a selection of different widths that will fit that hinge bolt they supply. In our case even when we had the washers perfect we had to grind the left side swing out because the holes were not aligned correctly from top to bottom of the ARM bumper frame.
We also used two long GR8 carriage bolts and washers through the entire bumper and frame instead of using their hokey banjo washers with the little segmented extension arms that they want you to insert into the bumper space. Here you see the GR8 bolts inserted. The weird banjo with cage nut on the left was discarded. Many benefits to this and the only downside I can come up with is that you have one bolt instead of two in case of failure. The forces that would be required to shear this GR8, once you see how it fits through, would be so incredible that you'd have bigger problems than this bolt to worry about
There are so many things unclear or wrong on the instructions that I wouldn't do much more than skim them along with each step to get the rough idea. It seemed that much of that stuff was from a 100 series that they just carried over but is wrong for our trucks? You're going to have to just hold it up, visualize it and then use trial and error.
You'll want a hoist for the alignment.
