Top fixed insert in track of bifold door

A quick learner from Boca Raton, FL says:
Hi. The fixed insert in the track of my bifold door, against the frame, is no longer fixed. Of course I broke it trying to fix it better. It's plastic and I fear that I used a screw that is too large. So now it slides an inch or so away from the door frame, although it remains in the track. I can move it back against the wall manually but it does not stay fixed. I am a senior, and though handy, I cannot figure out the name of this part to replace it. Do I need to replace it? Can you help me? I am still staying home because of COVID so I do not go to stores. Grateful for any help. Thanks

Thank you for your patience while we looked into this. I'm afraid your part is discontinued and is no longer made. The only parts we have that may work are our 21-204 and 21-175, but there's no guarantee either will ft. I am sorry that we cannot offer anything better.
