Suggestions for a way to replace broken antiquated shower door hinge

[buck116]

I’m new to the forum. Great to be here.
I never looked at my shower door hinges before, but now that they have broken, I may have discovered the dumbest shower door hinge design in history. Please see attached photos. They feature a single pin that runs the full length of the door frame, mostly hidden, and a hinge that is nothing but a piece of metal with a gapped tube at the end that wraps around the pin. Best thing is, the parts that ultimately keep the door on are small plastic pieces at top and bottom of each hinge. See photos. These things were created to fail. Anyway, I digress. The door has fallen off and the hinges are useless.
Can’t find any replacements for these or any info at all about them on the internet. Not surprising.

I’m desperately looking for suggestions on how I can fit another sort of hinge on here without having to completely remodel my shower. Any help is truly appreciated. Thanks for looking.

Those are called piano type hinges. Readily available at Big Box and hardware stores up to 6' that I've seen. Lots of ways to hinge any kind of door depending on what you have to attach to.
