Our 40-049 may work for you, but in my experience Larson uses our 40-188. I think your best bet, at this point, would be to take a few pictures of your existing handle set and upload them here for us to see. I would also like detailed dimensions. Thank you!
A quick learner says:
Here is the picture with dimensions as requested.I am also hoping to get the same finish as current.
DFA Plate mounting Screws spaced at 7-1/8 inches.
Backset: 7/8 inch
Face Plate: 13/16 x 7-3/4
Face Plate Screws: 6-15/16
Thank You

Looking at your dimensions, it does seem like the 40-049 is a good match. However, I believe that in the past, some customers did use the 40-049 as a replacement for the DFA and Emtek but had trouble installing. This is because it was not the same exact lock. With that in mind, you might have to retro fit it into your door. You may want the help of a local professional if you do not have experience with this kind of hardware.
