I have these really old bifold doors and need parts. Unfortunately, I've no idea of the brand or model. I'm looking to buy the upper and lower pins for the open side of the doors; I've attached pics of the parts I need, as well as the inside of the door. I see some similar parts on your site but would really appreciate your suggestions.

Thank you for reaching out to us. I recommend you have a look at the 21-043 guide pin. Compare our specifications with yours and see how they match up. The assembly comes with a spring and palnut. You can use the 21-157 spring retainer as a replacement for the palnut.
