I am looking to replace one of the bottom pins of a very old metal bifold door. The marking on the inside of the door says 1968 with the company name Float-Away Door Company. I could not find any markings or numbers on the existing pin.

This is definitely an older part, but it looks very similar to our Float-A-Way brand 21-033. Look this pin over and let me know if you agree.
