Metal Bifold door hardware replacement

A quick learner from NAPLES, FL says:
First two pics are of the broken bottom pin. Last pic (on the right) is from another door that is not broken. Can you help? Doors are from about 1973 vintage. Thanks.

Now that I look at my post again, the first photo (on the left) is the door that is working. The next two are of the one that has broken. Just need to know what parts to get to fix it. Can you help??

Hello, Helen. I feel confident that we can replace these pins, but we'll need a bit more information. First, can you tell me the diameter of the metal pin itself for the broken one? I'd also like to know the diameter of the cap that goes into the track bracket.

In the meantime, look at our 21-007. This is similar in design, I'm just not sure about how it compares in terms of size. It has a 1/4" diameter metal pin and a 3/8" diameter cap. Look it over and let me know what you think.

You can also see our entire selection here, in case you wanted to browse our other options.

The picture of 21-007 does not show the spring but description says spring loaded. Is the spring included? I'm thinking I will replace all the pins on one door. If it goes well, I will place another order and replace pins on all 6 doors (I have 3 sets). It appears I will need 21-007 (3), 21-001 (1), and 21-154 (1). Is that correct?

The 21-007 does in fact include a spring. The first image is showing the part compressed so you're not able to see it. 

I apologize for the confusion.

Installed all four new pins the door works great again. Planning to order parts for the other five doors and preventive maintenance. Thank you!
