Pella window crank

A quick learner from San Diego says:
What is the difference between 39-096-7 and 39-175-6?
Dimensions are the same. We need the crank on the left window in kitchen. The right was replaced by window repairman two years ago. The windows (which open outward) are more than ten years old.

The difference between these two pairs of operators is their link arms. You can see detailed pictures of each part on their respective pages. You will have to carefully compare your existing hardware to these pictures and in order to determine which is a better match.
