Thank you for the detailed dimensions and pictures. It looks like you have the old Cromwell bi-fold door. The bottom threaded adjusting pin for that door was our 21-003, the top pivot pin was a combination of our 21-026B plain pin with a 21-256 cone spring and two 21-155 palnuts. The guide pins were our 21-043, but with a 21-256 cone spring. Finally, the 1/4" white nylinder was our 21-150. Please review this hardware and let me know what you think.

Thanks Paul.
I saw you answered. I want to talk and discuss with u before I order. I saw a video where one bottom or top pin 21-007 can be snap to lock into the slots on a door. I like that and can hold the position to proper place IF IT WORKS FOR MY DOOR AND I HAVE SLOTS FOR THE SCREW WITH NOB SLIDES IN TO THAT HOLE . My hole on a door is not a square it is rectangle.
Can we use that instead. Please look all photos and guide me so I can buy.

Hmm... I'm not sure if you can use the 21-007 pin with that sleeve on your door. The only other part that comes to mind is our 21-043, with a 7/16" cap. The 21-007 has a 3/8" cap, which might be too loose in the track.
