I used a cherry picker (engine hoist) and some rope to manipulate mine. It's pretty easy to do that way, probably much easier than a floor jack, and it won't roll off on your head
.
This guy's videos helped me a lot. There are 3 parts. I welded 1/4" steel plates to the ends of the frame rails, with 7/16" nuts welded to the back. That keeps the frame rails from collapsing (so you don't need to use the sleeves on the bolts that go through the frame rails) and it gives a stronger point for the bolts into the end of the frame rail (where he put the flat washers which aren't much good for anything).

BTW: The ARB instructions are almost worthless. Watch the video and look at the forum posts.
