The only thing I'd add is when setting bolts, twist them the wrong way first, slowly, then await the "click" that you get when you're properly seated. This is frightfully and ever more so important with spark plugs! Thanks for producing the video and for offering a seemingly-appropriate price point.
Look after looking at the factory grab handles on the JL Wranglers I can't help but wonder why someone hasn't made a nylon handle that screws into the JK front pillars. You see, if I'm going to hit my head into a grab handle in a wreak, i'd much rather hit a Nylon handle than a solid steel grab handle.
