Thanks for contacting us! It's hard to say exactly what you need without seeing the original handle. I am also not familiar with that serial number. Could you give me the distance between the screw hole centers, center-to-center? I'd like to know what they are for both the inner and outer pair. Let me know!
6 3/4 from the middle of the top whole to the middle of the bottom hole. ( I can see that the handle was screwed in here.) 4 1/3 nothing was screwed into the top hole (There is an insulation that has not been punctured) and the bottom whole I am pretty sure is where the thumb lock goes in.
