It's tough to make out your mortise while it's still installed, but I think you may want something like our 82-268B. Look it over and see what you think. If it would be possible to see the original out of the door, I can confirm that this is correct, but right now it's mostly just an educated guess.
Sorry to hear it didn't work. I'm afraid that we don't have another version of the 82-268B. When you say ours is too wide, can you confirm the exact size of your original for comparison? I'm not sure if we can find it, since I've never seen a skinnier version before, but I can try my best to track it down.
In the meantime, you can see our return policy here.
I'm afraid not. I need the exact size of your mortise in order to begin our search. So far, the 32-268B is the only size I'm able to locate. In order to make further inquiries I need precise measurements.
