I tried top show the part with a ruler. Attachment holes are 1-7/8 inches. The attachment bracket is 2-1/4" wide. A spring is missing on the underside. The lip that holds the spring is broken

Thanks for posting! This lock looks similar in design to our 90-240. It's not exactly the same, but it is close and I think it's worth considering. Look it over and see what you think.
