Hello! Thanks for reaching out to us. Your mortise lock here has a very similar design to our 82-226. I think this may be what you want, since our dimensions are so close. The face plate is a little longer on ours but I don't think that will matter too much.

Thanks for the response. The distance between the mounting holes on 82-226 are about an inch further apart than the one I need to replace. Any other suggestions.

I'm sorry for the confusion. I thought your diagram had the hole spacing labelled as 4-5/8". Was I mistaken?

The only operator we have that has a shorter hole spacing is our 82-218, at 3-11/16". However the design of the face is different and I'm not sure how well this would work in your case.
