This order was to replace Gemlux hinges originally installed as OEM on a 2005 Renaissance Prowler. The order was an exact match for the original hinges and intalled with no issues. The hinge pins were missing from the original hinges when I bought the boat in 2014 (they had used large safety pins to fix). I finally got around to replacing them. The another set of original hinges was still working properly, but I replaced them as well.
