Attached are photos of the top of the metal bi-fold pivot. I also needs some of the threaded parts for the bottom pivot. At minimum, I need (4) springs, caps, and the best device to hold in the pin. The pin is 5/16 (.310) x 5 1/4" long.
I was looking at parts
21-065,
21-001,
21-007, and
21-154? I noted in the video that one of the devices had a metal piece that snapped into place to hold the pin.
Please advise on the correct parts
