Dave Sr. from SWISCO responded:
I have a feeling your operator is the Stanley 39-058 operator. My only concern is the difference in dimensions. Please recheck your measurements on the two lower installation holes. The 39-058 is 1-3/8" hole centers, not 1-3/4" like in your drawing. I also recommend that you remove your operator to check on the arms and linkage. You can see the dimensions for these features on the 39-058 store page.
