Internal latch

Question

I am searching for an internal lock for our door. I do not have the old one anymore. Inside mounting holes are 3 11/16, depth is 1 5/8, opening is 4 1/4 X 13/16.

Thanks for posting. Without seeing the original mortise lock I'm afraid it's difficult to say with any certainty what you need. That said, since the screw bosses are inside the door I suspect you might need the 82-244, which mounts in a very similar way. Double-check the dimensions below, compare with your door, and see if you think this might work for you.
