Two Needed Parts for Bi-Fold Mirror doors.

A quick learner from USA says:
I have enclosed , via attachment, photos of the two needed parts. I also provided you some measurements and descriptions of these items. They are as follows:

1, DISK (Function: A "push pin "apparently seats inside, this disk, while it rolls/slides along inside the tracks.

The dimensions of this disk are as follows:

A. The total diameter is 7/8's of an inch.
B. The thickness is apparently 1/8 of an inch.
C. The one side is flat
D. The other side is flat and has an elevated (1/8) of an inch diameter ring, the unit is monolithic. Furthermore, the 1/8 elevated diameter ring has an approximate O.D. of 7/16 with an inside diameter of approximate dimension I.D. 1/4, that the apparent spring loaded pin seats within it.

2, CORNER BRACKET/MOUNT (Function: This unit is positioned at each of the corners of the bi-folding doors. They house the "push pins and or the stationary pins."

The dimensions of this Corner Bracket are as follows:

A. The side measurement is three (3) inches.
B. The thickness of the unit is 1/2 inch.
C. The height/elevation of the unit is two (2) inches.

Distinguishing features to note on the unit.

A. The unit has two arrows on the top of it.
B. There are three screws that hold it in place, two on the bottom and one on the side.
(Please Note): I left the screws in the unit when I took the photo to help identify.

Thanks for posting! Based on your photo and description, I think you should consider our 21-174 roll guide as a replacement. Both the inner and outer diameters are the same and I believe it will work in the same capacity.

I'm afraid that I don't recognize the second part. Can you show me a photo of what it looks like while installed? Maybe context will help me find a match.
