Replacement sliding glass door hardware

A home owner from San Jose, California says:
I have looked on your site and found Legacy Handle Set 82-034. It looks identical to my lock set, except 1)I don't have a lock on mine, 2)my flip latch is dead center, not below center, 3)the mechanism mounts from inside the door frame with 2 screws.
I am including 2 photos for you to look at. Please advise what you might have to replace my existing hardware. It appears to me that the mechanism is broken. I removed the handle set and tried operating the mechanism with a small screwdriver and the latch just flops around. So perhaps I only need to replace the mechanism. And if so, How do I remove and replace it?

Thank you for posting on the discussion board and submitting your photos.

In my opinion your handle looks okay. I recommend you replace the inside mortise lock only. Take a look at the Swisco 82-218 Mortise Lock.
