I need to replace the window crank. The clip is at the bottom, I saw the name "Wright" on one of the parts. I need one for the left and one for the right (two different windows). Will part number 39-317 and 39-318 work?

I don't think the 39-317 and 39-318 are what you want. The link arms on yours are installed above the gear arm, while on our operators it's the other way around. See our 39-387 and 39-388 instead and see how well our dimensions match yours.

I had the same problem, The one 39-387 is 1/2" too long. They don't make it anymore, and they do not have the correct reference to the wright part number 07900. I will try to adapt the 319-18 to work.
