One of the bifold doors hadn't been working. In continuously lifting it up to close it I bent the top pin (the one with the spring). The door came off and comparing it to the one on the other side I definitely need the plastic "thing" as shown in picture 21-058. The only thing I see inside the doors informationally is this number: S 247618. I think that's a quality control number. There is also a Part No. 8433..............Please help..
Thank you
Ingrid
