Thanks for posting! I agree, this looks very similar to our S140-20. However, I'm not sure what you mean by window hook. Can you be more specific? Could I see a detailed picture of the hook in question?

Our S140-20 can be used for both the left and the right.
A quick learner says:

Oh I see. Thanks. I see how our S140-20's pivot shoe is a little different. You may want to replace the pivot bars, as well. How about our 26-398 & 26-405? Could you use either of these?
