Leigh Full-Vu Bi-Fold door pins

Question

I am trying to help my father-in-law fix his closet door. My best guess is that it is a Leigh Full-Vu Bi-Fold door. The home was built in 75 and the doors are metal. The pins seems to be worn (possibly some broken parts). I was wondering if these four parts are what's needed to replace the four pins on a single door (and, do I need to replace all 4 pins? Or just the top two?):

Hello,

From what we can see in your photos the pins look fine but you may want to consider replacing the nylon guides with our 21-108. To do that, you will need to remove the track to slide in the new guides. It wouldn't hurt to spray the track with some silicone spray. You should also check the alignment of the doors to determine if you might need to raise or lower the door by adjusting the 21-048 threaded bottom corner pivot pin. Thank you.
