Plastic bi-fold door bottom track glide - lost

A home owner from SC says:

I have a 25+ year old mirror glass dual bi-fold door. I'm missing one of the four little round "glides" that go on the ends of the guide pins and ride in slots in the sides of the top and bottom tracks.

The logo on the door mounting hardware says "Acme" with the number 17-1405.

When I Google that part number, Amazon pops up something similar, but the dimensions are wrong. My glides are 13/16" in diameter. The rim that rides in the slots is about 3/32"thick, The hub in the middle is almost 5/16" thick, with a 1/4" diameter cup in the middle.

Thank you for your help,

At first glance, our 21-174 roll guide seems to resemble your part. See if this is a match.
