first 2 sentences in my quote buddy , not to mention every other post in the thread buddy,the guy asked for help choosing a safety product he didn't come looking to be fed a line of BS about not needing it if you drive like a nancy boy , Like I said Baxter the main thing is securing the piece so it won't spin in the case and fail thats why the 904 doesn't have the same problem because they use a rivited or bolted piece to begin with
