Are these your parts?

Thanks for posting. I'd like to see the arms extending from your operator to the window to confirm which operator you need. Without that, I'd suggest you take a look at our EntryGard Dyad operator, Product Code; 39-036 and our EntryGard Dual Arm Operator, Product code; 39-032. Compare your dimension to ours to see which is the better match. In either case, you can replace the cover and handle with our 39-107 and 39-114L.
