Replacement part for US Plywood Metal Bi-Fold doors

A quick learner from Canada says:

Attached is a photo of the lower part of one of my US Plywood Metal Bi-Fold doors (that are about 45 years old).

The circled area shows the clamp which is tightened to the guide pin to keep that pin in place. I have lost that clamp and I have not been able to find a replacement for it.

From your website, I believe that part # 21-154 (a pivot rod clamp) can be used to replace my missing clamp. Is this correct?

If not, please let me know if you have a part that will replace my missing part.

Does the door have to be removed from the closet to replace the missing part?

Yes, the door must be removed to replace the part. As for the part itself, I think you have an older-style rod clamp that has been replaced with our 21-154.
