Older Stanley Metal Bifold doors

A home owner from Florida says:
I need your help getting some new tracks and hardware for these doors. My opening is 4 Feet!
Can I use : 21-453 tracks for top and bottom?
Can you also advise what replacement pins I can purchase that would work with the doors and this track?
Thank you,

For the tracks, see our 21-453 low profile (1/2" high) and 21-463 high profile (1" high) and see if these can work. Either one can be used for top and bottom, just make sure to match their heights to your old track. The other components you might need are our 23-112 spring loaded guide pin and 23-113 bottom door pivot. No need to replace them unless yours are worn out.
