Hello,

Thanks for posting! You have the old National bi-fold doors and we do carry a few of their parts in our inventory. If the tracks are still in a good condition, you'll need to reuse them.

Take a look at the 21-046 National Bifold Door Bottom Pivot and the 21-041 National Bi-fold Door Pin Assembly. As for the spring loaded guide pins, we only have the top nylon caps; the 21-113 National Bifold Door Pin Cap.

Carefully review and compare each of these parts to determine if they are the right fit for your door.
