Correct parts to order?

A quick learner from wisconsin says:
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

You have an old Slimfold model bi fold door. For the bottom threaded pin, you can consider our 21-001. For the top pivot pin and even the top and bottom guide pins, see our 21-007 instead. Your pivot rod clamps look fine and are used to lock the pins. If you need them, see the new type, 21-154.

What about the spring(s)?

Sure! Look at our 21-252 cone spring for the older Slimfold pin. I see you already bought a 21-106 cap. Please note the tip of the old pin needs to be 3/16" in diameter to accept the cap.
