Replacement Crank Components

I'm not sure what component you need exactly, but based on your photos I would wager you need a new hinge. See our 36-048 for a possible match. As long as the base track is 10", and as long as you replace the top and bottom at the same time, I'm confident this will work for your application. Look it over, as well as the video below, and let me know if you had any questions.
