Hello, As long as the dimensions below match up to yours, the 39-031 and 39-032 EntryGard operators would be the correct replacement. Not all of the holes would need to match up since not all of them are used for installation. You could also drill new holes in the window sill if needed. It also looks like the assembly shown in your photos would be the 39-032 since the gears are mounted on the right side of the worm gear. Thanks for posting! Dimensions for 39-032
