I am missing both guides on one of the shower doors. (Never had one, put the other aside at one point, and now can't find it)

I don't know the door manufacturer, and from looking at how the guides attached, I so far have not had luck finding anything that looks like a match. It is ~2 inches between the screws.

Any advice on what I need here? Who makes the doors, or better point me to the needed hardware? Other forums to try?

Attached here is a close-up of the guide mounting on the bottom of the door. I will post another picture on this thread with a picture of the doors.

Thanks!
