Hello, The shorter link arm that attaches the operator to the sash reminds me of our 39-333 and 39-334 but these replacements also have a long straight arm that attaches to the window as shown below. I can't make out if the operator you're replacing has an additional straight arm like ours based on your photos. If it does and the dimensions below match up to yours, then these would be the correct replacements. If not, let us know and we would be happy to research this further for you. Thank you! Dimensions for 39-333
