how are these drip rails attached?

I have a framed Aqua glass shower door that I need to replace the drip rail and vinyl sweep on. Do you mount it with mounting tape? My other one was screwed in but these holes don't look like they would match up? Or do you drill your own holes? This 30" rail looks like it might work if I can figure out how I would attach it. Thanks for your help!

Thanks for posting. The 10-325 is mounted with screws. I honestly can't say if our holes will match up, though. It's possible you will have to drill new ones, yes.
