Metal Bi-fold door

Question

The mechanism that holds the bi-fold metal door in place in the top track is broken.

Inside the door is a label that says:
Evans Products Company
Door Systems Division
Roseville, Michigan 48066
Model "E" Door - Oct. 25, 1976

The metal unit that keeps the door in place will not tighten/secure with a screw anymore - 10-32 screw just spins, and door leans.
I think this company is probably out of business. Any help with a replacement part would be greatly appreciated.
Let me know if you need more photos.

THANKS,
Wendy - frustrated homeowner

Hey, Wendy, hopefully I can help. I recommend that you start by looking at our 21-007 top pin and 21-200 pivot bracket. As for the other part you need, it might be our 21-001 adjusting pin. Check out this hardware and see what you think.
