82-218 looks like the correct latch. However, the old latch is attached to a frame that inserts into the door. The frame / latch assembly screws to the inside frame of the door.the latch ends up being recessed in the door about 1/4 inch

Hello,
Take a look and compare the specifications of the 82-244 mortise lock with a recessed faceplate to yours. Thanks for posting!
