Attached are photos of patio door and handle. I do not have the mortise lock or of the strike plate or of the lever for the lock. I want to replace these and the handle itself. The opening for the mortise lock in the door is rounded at top and bottom and the screw holes above and below the opening are 7 13/16 apart. The opening itself is 6 1/2 inches high. Screw holes for the handle are 4 13/16 apart.
There is a spring-loaded carriage inside the door that blocks off these holes unless lifted (photo shows screw driver holding it up). Please let me know what I need to keep the door and replace all the hardware in similar color
