Mounting a Crack Machine

Ok i just need a little help on mounting my crack machine. I have a fully adjustable crack machine its 8 feet tall. I just don't know how to mount it to the wall and keep it adjustable and not want to wobble around.

I've seen some mounted by one of the sides of the crack. If you fix one side of the crack to some framing which is mounted on studs in your wall you can adjust the other side. (I'm assuming this is a crack machine that uses some type of all-thread and spacers to adjust width)

Thanks for the information. I was thinking about doing this but wasn't sure if some climber has an awesome secret way to do this.
