Round corner shower enclosure (manufacturer unknown

I live in Maryland and need replacements for the plastic shower door guide affixed at the top of the door. Please note that one is missing. I need a like kind/compatible replacement. Please help. Thank you.

Thanks for the prompt response. When I went to install the doors I realized that those guides are on the bottom, not the top as indicated in my original post. Will the guides you recommend work on the bottom? Advise. Thanks.

I've also had to replace a few of the shower door roller guides. They seem prone to break around the nut that secures them.
I've found that this usually happens when a guest tries to pull the shower doors open rather than slide them as they should.
The replacement kit from Swisco I bought last year has been an improvement over the original ones that came with the shower.
I found that the new ones with the wheels on the bottom track are actually better than the original hook clip type and they work just fine.
I'm ordering today to replace another original clip that has broken on the second door and replace all to upgrade the entire door unit.
Swisco does seem to be a bit expensive on the kit, but they are prompt and accurate in their shipments. Sometimes quality and service are worth a premium.
