Bi-Fold Door hardware replacements

A quick learner from Indiana says:

Doors are 36w x 93.5L

I would like to eliminate the bottom track period on it and it be top track only. There is no markings on any of these pieces. I need to know what I need to order for the doors parts wise.

Regardless of the outcome of this post I will need new tracks as well. These doors are 49+ years old and the tracks are cracked and split apart.  So if there is a kit where everything is including that would be the way to go

  • The two with no threads are 5 1/4 long
  • The one with threads is roughly 5 1/4 long as well. It's bent so an exact measurement can't get.
  • The one with the spring is is as well 5 1/4
  • The diameters are 5/16 on all

I noticed you have the older style Slimfold bi-fold door hardware. You can use Slimfold's newer style hardware parts for your door. You will need one of the 21-001 bottom threaded pivot pin and three of the 21-007 spring loaded pins. Look these parts over and see what you think. I will also associate a video below that shows how these parts are installed.
