Bi-fold Door Bottom Pivot Bracket

It is 30 inch bifold mirrored door. I need track both for top and bottom. I need the gliding roller that glides inside the track and whatever hardware that goes along.

Most replacement parts do not have the pivot caps. Therefore we can't use the standard replacement pivots. The size of the cap is 1 1/2 x 1 1/8. We will need eight top and four bottom pivots.

This is a Stanley monarch full mirrored bifold door. I'm looking for the top and bottom are the same plastic roller that fits inside the track photograph is of the top. It's in fairly good shape. The bottom one has disintegrated completely away. The plastic part it's about 3/4 of an inch wide by 1/4 ... (cont.)

I was thinking maybe a metal plate across the bottom of the door, with a screw to replace the pin the first picture you can see where the door on the right has the pin in place as needed. The one on the left is the one that is missing the bottom pin also a close up of the pin

I need a bifold door top bracket that is wider than the 7/8 in brackets commonly available. The interior of my top channel is a full 1 inch. A 7/8 in top bracket slips out of the lower flanges of the track. Thanks!
