48 inch track for old bifold metal doors

Question

Good morning,
Looking to replace the top and bottom tracks (48 inches) for a closet with metal bifold doors. The house was built in the 70s. Please see attached pic of one of the closet doors and please confirm if product # 21-404 will work. Thank you.

I'm afraid I can't confirm that our 21-404 can work or not. That depends on many factors and just seeing the door doesn't tell me anything important at this stage.

To start, I'd like a clear photo of the original track shown from the end profile, just like how we show the 21-404. I also need you to show me a photo of the pins that will be interfacing with it, along with written, precise dimensions. The diameter in particular. Would that be possible?
