The knob handled needs to be glued. The lock hook is not staying in position, one must re-adjust the hook so it stays in the correct locked position. The door is 33 years old as is the house. We had the house built in 1986.
Total length of black interior piece is 7 3/8"
Distance between the two screws is approximately 4" This sliding glass door has been on our house since November 1986 when the house was built. The door still works and rolls perfectly today.

Hey, Charles! It sounds like you're having trouble with both the thumb lever and the mortise. The mortise is easy enough; yours looks like our 82-218. I'm very confident this will work in your door.
I'm also confident in what will replace the thumb lever, but the bad news is that we're no longer able to supply it by itself. I'm afraid we can only offer the complete handle set at this time; specifically, our 82-033. This should work the same way as your old handle and is fully compatible with the 82-218.
You are very welcome. We are happy to hear that everything has worked out for you.
