Looking for Roller Assembly as shown

A home owner from Palm Springs California says:
These are from circa 1965-1970 and go on the bottom of floor to ceiling mirrored closet doors used in apartment buildings in Palm Springs, CA. There are three doors (1 mounted on rear of track, two mounted on front of track) and the front-mounted doors need to slide past the middle (rear-mounted door).

I have not been able to find replacements with the mounting flanges in the "center" of the housing. What I'm finding are ones with the flanges on the outside or inside but these keep the doors from being able to pass each other on the track.

I think I see what you mean. How about our 23-064? The tabs appear to be centered in the housing. See what you think.
