Point of clarification:
My comment was directed at Jon. I only saw his double jack setup and safety explanation. I realize that I used the phrase "people" in my comment, but I had only Jon's preaching sentence about Liberty and his (otherwise good) DIY posts in mind. I made the mistake of not explicitly addressing Jon in my comment. I am sorry Mike, if you care. Regarding Roger, I have no clue who he is, I have no recollection of his previous posts and had no idea that he also replaced airbags.
