Heavy Bifold door track

A home owner from USA says:
I need to replace a track for a very heavy 72" bi-fold closet door. I believe the track that the installer used, was not meant for a solid wood door and became bent. It would no longer hold onto the round head. I was looking at: 72" Bifold Track, 4 Door (7/16" pin)
Product Code: 23-456

which looks like it would work and be a much better quality. Looking at my photos are you able to tell if that's correct, and do I also need to replace the other parts in order for everything to function together? Thanks!

The top fittings you show me look like our 23-112 top pivot and 23-114 top guide roller. They are used on our 23-512 track, though, and won't work in our 23-456 . To use the 23-456 , you would also need our 23-121 for the top pivot and top guide. The 23-512 track can take up to 30 pounds and 23-456 can take up to 35 pounds.
A quick learner from California says:
Thanks, that's very helpful. So I will go ahead and order the 23-456 and then I would need a total of (4) of the 23-121 ? Looks like the guide cap comes off so the same product is used as the top pivot?

For the 23-121 , use the same pin with cap. There's no need to remove the cap.
