Removing the bolt there are several methods. Since about the only thing I have access to is easy outs, which don't work all that often. I would take the adapter to a machine shop and have someone do it for me. They can maybe get it out and chase the threads, or drill out for larger size and re tap or heli-coil it.
For installation I use either an ATV jack, tranny jack, or floor jack with a plate. I know some have used an engine hoist from the interior. I also used a come along that was attached to my cage from the inside. All depends what you are comfortable with. Good luck.
