Funny, bought this last year and just getting around to installing it. But first, had to remove the old swivel and that bolt was just not budging, evening after various chemical treatments. Took to the internet and the general consensus was, cut the last link off with bolt cutters. Worked like a charm. Now have the new swivel and ready to try it our in Silver Lake, Ocracoke.
