Old metal bi fold doors

Question

The correct pin for bottom float away is 21-033
I ordered 2 tracks, which are narrow (1/2 ") wide instead of 1" wide.
I need part number for 1" wide and 7/8th high track ,
I also need correct part number for the pivot bottom pin. The one I ordered did not work.
I have received the following items already.
I have the old top track. The top bifold door guide pin is working.

The following items are included in this shipment:
-------------------------------------------------------
(4) 21-007 : Bifold Door Guide Pin
(1) 21-401 : Bifold Track, 3' Opening
(1) 21-402 : Bifold Track, 5' Opening
(6) 21-001 : Bi-fold Door Pivot Assembly
(6) 21-154 : Pivot Rod Clamp
(2) 21-277 : Bifold Track Bumper

Will the narrow tracks work?
Thanks for your help.

Hi there, Nasreen.

Thanks for reaching out to us. I'm afraid this information isn't enough for us to ID your hardware. We will need to see photos of your old track and each pin removed from the door in order to help. We will also need you to write out the diameter of the pin shaft and the diameter of the nylon cap, where it fits into the track.
