Replacement crank window system

A home owner from New Hope, MN says:
Our 2 crank windows won't close if they have been fully opened. We can't find a left and right replacement system on your website. We have attached a photo. Please advise

Your operator looks like it could be a match for our 39-221B and 39-220B. Look these two products over and let me know if you agree.

Note that if you cannot reuse your old cover, you will also need the 39-451 and 39-452, respectively.
