Bifold door track for old Fenestra doors

A handy person from Havertown, PA says:
Hi, I'm looking for the track to rehang old Fenestra metal bifold doors. Each opening fits 2 doors. Each door measures 24 inches. So I guess I need a 4' track. Would your 4' track work with these doors and the pins pictured. Thanks for your help.

Take a look at our 21-404 track that accepts a 3/8" diameter pin cap as shown below. Confirm that your pivot pins have the same size cap as shown below and you should be good to go. Thank you!
