1998 Sliding glass door
Thanks for reaching out to us. I'm sorry to say that I don't recognize this door make, so I'm not sure who made it or what parts it may use. what I can tell you is that we don't sell any handle set with a 6-5/8" hole spacing that would fit on this kind of frame.
I think at this stage you should consider installing a surface-mount set, like our 82-005. This product has a self-contained mortise, which means it doesn't have to interact with any specific hardware in the door. It just screws right to it.
The downside is you will need to drill new installation holes, both for the handle and for the keeper. This also assumes you have space on the frame for a keeper so be sure to check that before you buy anything. The video below will give you a better idea of how this hardware works.
