Hey there!

Thank you for your patience during this busy season. Our 39-375 and 39-376 cover and handles will not work for your operator. These are meant for operators with splines that sit to the left or right of the assembly, while yours is dead center. Take a look at our 39-107 cover instead. This should be a better match for what you need.
