Shower glass door part

Hello,

I can't be sure but your bumpers remind me of the ones that come with the 10-058 kit shown below. If you could show us the rollers that your door uses, that would help us confirm. Thank you! 

Thanks for getting back to us. We did carry the roller shown in your photos at one time but, unfortunately, it was discontinued along with the guides used with them. I'm sorry that we won't be able to supply the replacement part that you need but please let us know if you have any other hardware questions. Thanks for posting. 

The part in your first two photos is a lower guide used with this assembly, which was also discontinued. The other part is the same guide shown in your original photos, which cradles the door from below. I'm sorry that we won't be able to provide these replacement parts but you could track checking with local hardware stores that have been in the area for a long time to see if they have any backstock of these shower guides.
