Metal bifold door I

Hello, thank you for posting,

We assume your tracks are fine, since you only need the the pins. So for your top and bottom guide pins, you can use the 21-054. For the bottom and top bracket on your track, 21-206. For your bottom threaded adjusting pin, 21-062. This pin will raise, lower and square up your door. For the top plain pin with spring, unfortunately we don't have, but if you use the 21-054 and reverse it or remove nylon cap, you can use it.

Let us know if you have any questions!
