I think our 82-218 is the best match for you. I've heard the same story from a lot of customers who tried this part out, but it always ended up working in the end. I think the manufacturers designed it to be a little tight. I think if you keep at it, it should work. Just be careful during installation not to let the mortise lock fall into the door. See our video below on how to prevent this from happening.
