Installing the 23-215

Thanks for writing in. The 23-215 guide installs in one of two ways: either it screws in using those small holes you see, or it hooks into the door using those top hooks on its body. In my experience most mirror closet doors use the hooks. We rarely see these installed with the screws, but it's a possibility to keep in mind. Let me know if you have further questions. 

I'm sorry to say that I have no reference to that kit in our records, so I'm unable to verify whether the 23-215 is the part you need or not. Seeing photos of the original guide would give me a better idea of what you're working with. Is that something that you can provide?

Otherwise, you may want to contact Stanley directly. They'd be in a better position to tell you what is and isn't included in their kits. We don't have access to that kind of information, we can only identify parts based on user-submitted photos.
