Shower enclosure coming apart

[Pnewman10]

On the last trip in our 2020 Entegra Anthem, our shower enclosure starting to get a little loose where the head rail (that is what I am calling it-the rail over the top of the door itself that secures the door and the corner of the fixed piece of shower glass) mets the wall where the door itself swings from. I should have not been lazy and tightened the little screw up on the top that tightens into this little block that slides inside the jamb against the wall. Instead, I taped everything up with gorilla tape thinking I would fix it when we got hope. Well, when we got home I removed the gorilla tape and opened the shower door which then it (the shower door), proceeded to fall onto the floor. Somehow, it did not break. I called Entegra and they are trying to figure out what part I need to fix my problem. The little part that fits inside the jamb rail that the headrail screws into is a little piece of what looks like a black teflon material. I would send a picture of it but I let it slip down into the jamb rail. Has anyone had this issue? If Entegra can't figure out what the part is do you think making a little stainless steel bracket and attaching it to the head rail and the wall would work?
