Shower door connectors

A handy person from Florida says:
Hi
Some of the hardware on the bottom track of the shower door In my rv are broken. They are on a track that holds the 3 glass panels which make up the retracting Shower door . Can you help me to identify and get the parts I need?

It's hard to tell what this is while it's still attached to the door, but it might be our 10-074. See what you think.
