Please help,,,I have had zero luck with this??
This one looks to me like it only attaches from the front side and there's only a little tiny thing outside that doesn't attach to this one ? If you look close you can see a little emblem I don't know if it's a double M or a double W maybe you can see it better than me

Hello,

Take a look and compare the specifications of the 82-080 handle set, along with the related items, to your assembly. 

It's hard to say what mortise you have with it still installed but I think the 82-268B would be a good place to start. Thanks for posting!
