I need to identify which pin is most fit my case.

It is top pin in the middle of two sash. I won't to remove such old one.
sometime it will not be back if removed. So I have to show you the picture.

The door is made 60's but the pin might already not original. I tried some pin on market
but failed. Thanks for your help.

You have an old Float- A-Way bifold door. You're in luck because we still offer some replacement parts to accommodate these doors. Take a look at our 21-033 threaded pin with the nylon cap. We'd also like for you to look at our 21-035 bottom threaded pivot without the nylon cap. See if either of these would make a good match for you.
