A distributor from Wixom MI says:

I have a customer with a patio door that is 1" thick, the overall dimensions of his existing hardware is 8 1/2 inches long, and the style looks just like the 82-034 legacy set that you show here. My concern is that you show the door thickness as 1 3/8" unless I am looking at it incorrectly. Can you please tell me if this hardware will work on the installation I have attached below?

Yes, the 82-034 is meant to work on doors that are 1-3/8" thick. 1" is pretty skinny for this kind of door, to be honest. You may be able to use the 82-034 regardless, but you'd have to cut the spindle on the key cylinder and thumb turn to size. You would also need the appropriately sized screw. Even then, I cannot guarantee that it would work.
