Two things that I believe that they Do Not explain about this conversion.

1: You lose the used of the Horn Button on your Steering Wheel as there's no place for the wire to run out of any more, because the end of the Hollow Shaft is now welded over.

2: There's a Rubber Bumper Stop mounted on the Frame Rail for when the truck Bottoms Out, that they Remove because it's in the way & it's removal has caused some problems for me & others.
